After 32 years from now a boy will be 5 times as old as he was 8 years back.How old is the boy now?
Answers
Answer:
18 years
Step-by-step explanation:
Transforming the question in form of equation:
Let x be the current age.
x + 32 = 5(x-8)
x + 32 = 5x - 40
5x - x = 40 + 32
4x = 72
x = 18
Answer: look at this! He’s 18
Step-by-step explanation:
equation = x+32=5(x-8)
X+32=5x-40
5x-x=32+40
4x=72
X=72/4
=18

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Let x be the number of $5 bills and y be the number of $1 bills.
From the problem, we know that:
y = 3x + 4 (since the number of $1 bills was 4 more than 3 times the number of $5 bills)
The total amount of money the man had is $36, so we can write:
5x + 1y = 36
Substituting the first equation into the second equation, we get:
5x + 1(3x + 4) = 36
Simplifying and solving for x, we get:
5x + 3x + 4 = 36
8x = 32
x = 4
So the man had 4 $5 bills.
Using the first equation, we can find the number of $1 bills:
y = 3x + 4 = 3(4) + 4 = 16
Therefore,
The man had 4 $5 bills and 16 $1 bills.

Monica has this recipe for fruit salad. 2 1/2 cups of pers, 2/3 cups of grapes, 1 1/4 cups of apples, and 1/2 of orange slices. How many cups for fruit is it in total?
Answers
Answer:
[tex]3\frac{11}{12}[/tex] cups
Step-by-step explanation:

[tex]\frac{2}{3}[/tex] of grapes
[tex]\frac{1}{4}[/tex] of apples

Answers
Answer:
8 inches
Step-by-step explanation:
Let w be the width of rectangle B.
Since, both rectangles are similar.
Therefore, corresponding lengths and widths of rectangles A and B will be in proportion.
[tex] \therefore \frac{20}{40} = \frac{4}{w} \\ \\ \frac{1}{2} = \frac{4}{w} \\ \\ w = 2 \times 4 \\ \\ w = 8 \: inches[/tex]
Answer:
8"
Step-by-step explanation:
Lᵃ/Wᵃ = Lᵇ/Wᵇ
20"/4" = 40"/Wᵇ
Wᵇ = (4"×40")/20"
Wᵇ = 160" ÷ 20"
Wᵇ = 8"

tangent
Answers
Answer:
tan
Step-by-step explanation:
you can use this equation
[tex]tan(18) = \frac{h}{100} [/tex]
to solve for h
Answer:
Tangent
Step-by-step explanation:
Tangent=opposite/adjacent
For the angle that's 18°, it's opposite side is h, and the side that is next to, or adjacent to it is 100. It's not the other side because that's hypotenuse.
When you plug those in, you'll have:
[tex]tan(18)=\frac{h}{100}[/tex]
Solve for h by multiplying both sides by 100 to get:
[tex]100*tan(18)=h[/tex]
Put [tex]tan(18)[/tex] into calculator to get .324919. When you do so, make sure you're in degrees, not radians.
Since we are multiplying that by 100, the final answer is 32.4919

If P=(2,-1),find the image of P under the following rotation. 180 degrees counterclockwise about the origin
Answers
9514 1404 393
Answer:
(-2, 1)
Step-by-step explanation:
Rotating a point 180° about the origin in either direction is equivalent to reflecting it across the origin. The effect is to negate both coordinates.
(x, y) ⇒ (-x, -y) . . . . . rotation 180°
(2, -1) ⇒ (-2, 1) . . . . . P' rotated 180° from P
The coordinates of the rotated point are (-2, 1).
