Answer:
7 yd
Step-by-step explanation:
The sum of horizontal measures is the same across the top and bottom:
15 yd = 8 yd + ?
7 yd = ? . . . . . subtract 8 yd from both sides
The missing side length is 7 yd.
Answer:
He sold 100 rackets for $ 20
Step-by-step explanation:
To start, we have to make 2 equations, one that represents the number of rackets and the other the money
x + y = 500
x * 20 + y * 45 = 20000
we clear x in the first equation
x + y = 500
x = 500 - y
we replace x in the second equation with (500 - y)
x * 20 + y * 45 = 20000
(500 - y) * 20 + y * 45 = 20000
10000 - 20y + 45y = 20000
-20y + 45y = 20000 - 10000
25y = 10000
y = 10000/25
y = 400
we replace x in the first equation with the value obtained
x = 500 - y
x = 500 - 400
x = 100
He sold 100 rackets for $ 20
Answer:
192
Step-by-step explanation:
Given,
a = 8
b = 24
To find : ab = ?
ab
= 8 x 24
= 192
Answer:
to do this question, add width + height. 4/6 + 2/5 are not normally add-able. So to correct this, we find the most common factors. There is 1, 5, and 6 at highest. 5 and 6 share a high number multiple if you combine them. This multiple is 30. So now, keep, change, flip.
4x2 is 8.
6x5 is 30.
I would say the answer should be eight thirtieths.
