Answer:
Red
Step-by-step explanation:
To solve this we can use substitution.
We know that y=4-x, so we can substitute "4-x" into anywhere that y appears in the first equation.
4-x=3x-8
Now we can move the variables to one side and the numbers to the other.
We can do that by adding x to both sides.
4=3x-8+x
Now, let's add 8 to both sides.
4+8=3x+x
Combine like terms.
12=4x
x=3
Now, we can plug that back into the equation to find y.
y=3(3)-8
y=8
y=1
So our answer is (3,1)
Answer:
x= -11
Step-by-step explanation:
1/2(x-8)=3/2x+7
distribute
1/2x-4 = 3/2x+7
subtract 1/2x from both sides
1/2x cancels out
-4 = 1x+7
subtract 7 from both sides
-11 = 1x (1x is the same as "x")
(b-5)+6
The difference of b and 5 can be written as b-5
If 6 is more than the difference of b <u>and</u> 5 then everything would be written as
(b-5) + 6
You start at 18 feet, go down to -14, go down 4 feet to -18 feet or C
Answer:
3/4 of the same number is 90
Step-by-step explanation:
FIND the unknown number by:
48 ÷ 2/5 = 120
TIP: for finding a fractional part of a number, multiply the fraction by the number. Like:
2/5 of 120 also means 2/5 x 120.
Find 3/4 of 120:
3/4 x 120 = 90
