Answer:
The numbers are 12 and 32.
Step-by-step explanation:
x = One number
x - 20 = Another number
3x - (x - 20) = 84 (If the lesser number is subtracted from three times the greater number, the difference is 84)
Let's solve for x, this way:
3x - (x - 20) = 84
3x - x + 20 = 84
2x = 84 - 20 (Subtracting 20 at both sides)
2x = 64
x = 64/2
x = 32 ⇒ x - 20 = 12
For the given problem, by denoting the lesser number as 'x', we can form and solve an algebraic equation to find 'x=12' and 'x+20=32', which are the lesser and the greater numbers respectively.
Explanation:This problem involves the concepts of algebraic equations. Let's denote the lesser number as 'x'. Therefore, the greater number becomes 'x+20' because it is 20 more than the lesser number. The problem states that three times the greater number subtracted by the lesser number is 84. So, we can translate that into the equation: 3*(x+20) - x = 84.
Solving this equation we get: 3x + 60 - x = 84, which simplifies further to 2x + 60 = 84. Deducting 60 from both sides gives 2x = 24. Finally, dividing by 2 gives x = 12 which is the lesser number. So the greater number becomes x + 20 = 12 + 20 = 32.

Select the equivalent expression.
(a-2.87)?=?
Two expressions are equivalent if we can arrange one of them in order to match the other. If we evaluate the two expressions for certain values in the input, we must get the same value in the output. In this exercise, we have the following expression:

2. Fred and Mary Merrill want to purchase a new car. The car has a base
price of $16,700, options totaling $1.095, and a destination charge of
$325. They read in a consumer magazine that the dealer's cost for the car
is 90 percent of the base price and 87 percent of the options price. What
should they estimate as the dealer's cost? *

To estimate the dealer's cost, calculate 90% of the base price and 87% of the options price. Add the dealer's cost of the base price and options price to find the estimated dealer's cost.
Explanation:To estimate the dealer's cost, we need to find 90% of the base price and 87% of the options price.
90% of $16,700 (base price) = $16,700 x 0.90 = $15,03087% of $1,095 (options price) = $1,095 x 0.87 = $952.65Adding the dealer's cost of the base price and options price: $15,030 + $952.65 = $15,982.65Therefore, the estimated dealer's cost is $15,982.65.

-7 = -1 + [tex]\frac{x}{3}[/tex]
To solve this you must isolate x.
On the right side of the equation the one is negative. To cancel the -1 from the right side you must add 1 to both sides (what you do to one side you do to the other) since addition is the opposite of subtraction (negative). Doing this will make -1 zero on the right side of the equation and bring it over to the left side
-7 + 1 = -1 + 1 + [tex]\frac{x}{3}[/tex]
-6 = 0 + [tex]\frac{x}{3}[/tex]
-6 = [tex]\frac{x}{3}[/tex]
The x is being divided by 3 and the opposite of division is multiplication. To completely isolate x you must multiply 3 to both sides. This will cancel the three out on the right side of the equation and bring it over the left side.
-6 * 3 = [tex]\frac{x}{3}[/tex] * 3
-18 = x
Now check:
-7 = -1 + [tex]\frac{-18}{3}[/tex]
-7 = -1 + (-6)
-7 = -7
^^^This is true which means that x = -18

17. Only tenth-, eleventh-, and twelfth-grade students
attend Washington High School. The ratio of tenth
graders to the school's total student population is
86:255, and the ratio of eleventh graders to the
school's total student population is 18:51. If 1 student
is chosen at random from the entire school, which
grade is that student most likely to be in?
Answer: Eleventh Grade
Step-by-step
The ratio of tenth graders to the school's total population is 86:255 = 33.7%.
The ratio of eleventh graders to the school's total population is 18:51 = 35.3%.
Since the probability of a student being in either tenth, eleventh, or twelfth grade = 1 = 100% (that is, certainty), then the probability of a randomly drawn student being in twelfth grade is (100-33.7-35.3)% = 31.0%.
When randomly choosing one student from the whole school, it is most likely (35.3%) that the student is in the eleventh grade.

600 miles in 8 hours
_?_ miles per hour
(number answer only)
Question
Answer:
75
Step-by-step explanation:
you have 600 = 8 and you want to break it down into just 1 hour so you divide both sides by 8
600/8 = 75
Final answer:
The student was traveling at a speed of 75 miles per hour.
Explanation:
To calculate the speed in miles per hour when a student has traveled 600 miles in 8 hours, you divide the total distance by the total time taken. The formula to find speed is:
Speed = Distance / Time
So, if we plug in the values we have:
Speed = 600 miles / 8 hours = 75 miles per hour
Therefore, the student was traveling at a speed of 75 miles per hour.

What is the area of the trapezoid? A trapezoid has a base of 12 centimeters, a height of 16 centimeters, and a top side length of 10 centimeters. 176 cm2 192 cm2 208 cm2 224 cm2
Answer:
176
Step-by-step explanation:
option a ( 176 cm²)
A trapezoid has a base of 12 centimeters, a height of 16 centimeters, and a top side length of 10 centimeters.
To find the area, we use the formula for the area of a trapezoid:
Area = 1/2 × (Base1 + Base2) × Height
Here, Base1 is 12 cm,
Base2 is 10 cm, and
the height is 16 cm.
the sum of the bases:
12 cm + 10 cm
= 22 cm.
Multiply by the height:
22 cm × 16 cm
= 352 cm².
Divide by 2 to get the area:
352 cm² ÷ 2
= 176 cm².
So, the area of the trapezoid is 176 cm².

Length = 12 m and width = [tex]\frac{7}{2}[/tex] m.
Solution:
Let the width of the rectangle be w.
Length of the rectangle = 2w + 5
Area of the rectangle given = 42 m²
Area of the rectangle = length × width
length × width = 42
(2w + 5) × w = 42
[tex]2w^2+5w=42[/tex]
Subtract 42 from both sides, we get
[tex]2w^2+5w-42=0[/tex]
Using quadratic formula,
[tex]$x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}[/tex]
Here, [tex]a=2, b=5, c=-42[/tex]
[tex]$w=\frac{-5 \pm \sqrt{5^{2}-4 \cdot 2(-42)}}{2 \cdot 2}[/tex]
[tex]$w=\frac{-5 \pm \sqrt{25+336}}{4}[/tex]
[tex]$w=\frac{-5 \pm \sqrt{361}}{4}[/tex]
[tex]$w=\frac{-5 \pm19}{4}[/tex]
[tex]$w=\frac{-5+19}{4}, w=\frac{-5-19}{4}[/tex]
[tex]$w=\frac{14}{4}, w=\frac{-24}{4}[/tex]
[tex]$w=\frac{7}{2}, w=-6[/tex]
Dimension cannot be in negative, so neglect w = –6.
Width of the rectangle = [tex]\frac{7}{2}[/tex] m
[tex]$L=2(\frac{7}{2} )+5=12 \ m[/tex]
Hence length = 12 m and width = [tex]\frac{7}{2}[/tex] m.
