This is a ratio problem; the ratio of the length to width is constant (and therefore equal):
4 /6 = 15 / x
Now, with a ratio, we may do any allowable algebra operation: cross-multiply, invert both sides, multiply or divide both sides by the same amount, etc.
Let's cross-multiply:
4x = (15)(6)
x = 90/4
x = 22.5 in.
Answer:
34 and 30
Step-by-step explanation:
8 times 3 = 34
and 34-4=30
divide 8 by 2 and you'll get 4
so, 34-4=30
Answer:
The third one, y=x-3
Step-by-step explanation:
A linear equation is any equation that can be written in the form. ax+b=0. Meaning it will not have a radical or be squared.
Answer:
y is 15 x is 3
Step-by-step explanation:
Step-by-step explanation:
Area of each paralellogram = b * h = 12 * 20 = 240 square inches
Area of 9 paralellograms = 9 * 240 = 2160 square inches
