Right now Seth’s age is 4/5 the age of his brother Eric. Twenty-one years ago, Eric was twice as old as Seth. What are their ages now?
Answer: We are told that 21 years ago, Eric was twice as old as Seth. So, Eric was 2{(4/5)x-21} years old 21 years ago (just multiply Seth's age 21 years ago by 2).

find the area of the trapezoid below
Answer:
18 cm2
Step-by-step explanation:
-2x/3 + 11 = 14 please help me its not letting me put stuff I want
Answer:
x = -4 1/2
Step-by-step explanation:
-2x/3 + 11 = 14
subtract 11 from each side of the equation:
-2x/3 = 3
multiply both sides by 3:
-2x = 9
divide both sides by -2:
x = -4 1/2
Joshua bought five apples and four oranges. The total amount he paid was at most Php 200.

Answer:
The answer is C
Step-by-step explanation:
You are a dress maker and buy many of your fabrics overseas. You have been given a new design for a dress that each dress
takes 1.5 metres of fabric that you need to buy from a supplier. You are making 12 dresses. The fabric is sold for $22.50 per
yard. How many yards would you need to order and what would it cost you?
Answer:
Total yards = 19.685 yards
Total cost = $442.9125
Step-by-step explanation:
Fabrics per dress = 1.5 meters
Number of dresses = 12
Total fabrics needed = 1.5 meters × 12
= 18 meters
Convert 18 meters of fabrics into yards
18 meters = 19.685 yards
Cost of fabric per yard = $22.50
Total cost of fabrics in yards = 19.685 yards × $22.50
= $442.9125

PLEAZE HELP IM FAILING THIS CLASS 9) The volume of a box is represented by x' +11x² + 20x – 32. The width of the box is x – 1, and
the height is x + 8. Find the expression representing the length of the box.
Answer:
Step-by-step explanation:
Volume of the box = x³ +11x² + 20x – 32 I think the ' is a typo for ³
the width is x-1 and the height is x+8
Find an expression for the length
Vol = LWH solve L
Vol / (WH) = L so
L = (x³ +11x² + 20x – 32) / (x-1) (x+8)
so it would help to factor the numerator
(x³ +11x² + 20x – 32) I'm willing to bet (x-1) and (x+8) are factors
but I will plot the equation to find the three roots
(x³ +11x² + 20x – 32) = (x-1) (x+8) (x+4)
L = (x³ +11x² + 20x – 32) / (x-1) (x+8)
= (x-1) (x+8) (x+4) / (x-1) (x+8) the (x-1) and (x+8) cancel out leaving
L = (x + 4)

Using the information that
5.2 x 67 = 348.4
write down the value of
c) 348.4 ÷ 52
Answer: 6.7
Step-by-step explanation:
We know that:
5.2*67 = 348.4
And we want to find the value of:
348.4/52 = x
So, let's return to the original equation.
5.2*67 = 348.4
Let's try to "construct" the quotient 348.4/52
The first step is to divide both sides by 5.2, then we get:
(5.2*67)/5.2 = 348.4/5.2
67 = 348.4/5.2
Now we have 5.2 in the denominator instead of 52, then we can divide both sides by 10 to get:
67/10 = ( 348.4/5.2)/10 = 348.4/(5.2*10) = 348.8/52
6.7 = 348.8/52
Then the solution to the quotient:
348.4/52 is 6.7

reduce:
12x = 12
x = 1
y = 3 - 8
y = -5
