Answer:
63
Step-by-step explanation:
first yoy need to put the biggest number on the top then multiply each number
Answer:
a=-8
b=-29
Step-by-step explanation:
Let's assume
first number is a
second number is b
the difference of two numbers,a and b,is 21
so, we get

we can solve for 'a'

the difference of five times a and two times b is 18
so, we get

now, we can plug 'a'

now, we can solve for b




now, we can find 'a'


Answer:
A
B
D
Step-by-step explanation:
A 230 divided by 4 is 57.5 which makes A a true statement.
B 296 divided by 5 is 59.2 which makes B a true statement .
D 296 - 230 =66
66 - 57.5 = 8.5
Which makes D a true statement by a margin of 8.5 words.
Just use your equation and sub in 1.5 for x (thee time) to find y (the height at that time). You get a height of 15.5 when the time is 1.5 seconds
Answer:
Let l be length and w be width.
First equation:
l = 2w-4
Second equation:
perimeter = 40 units
Perimeter of a rectangle: 2(l+w)
2(2w-4+w)=40
2(3w-4)=40
6w-8=40
6w=40+8
6w=48
w=48/6
w=8
Therefore the width=8;
length= 2w-4 = 2(8)-4 = 16-4 = 12
perimeter = 40 units
