I don't know for sure I'm going to ace grade next year but I know that you you need to put the coefficients with the same variable together and the variable next to the coefficients and multiply or add or divide or subtract them and you get your answer and this is just 7th grade math I'm relying on
The numbers will be X and Y with X being the lesser
x+y=45
2y=5x+6
now use a subtraction method to solve
x+y=45
y=45-x
2 (45-x)=5x+6
90-2x=5x+6
-7×=-84
x=12
y=45-12
y=33
so, x=12 and y=33
Answer:
x = -9.375
im not sure if i interpreted the times symbol right
step-by-step explanation:
2x + 30 = (30/10) • 5(2x + 3) + 87
2x + 30 = 3 • 10x + 15 + 87
2x + 30 = 105 • 10x
-2x -2x
30 = 105 • 8x
-105 -105
-75 = 8x
/8 /8
-9.375 = x ?
Answer:
A.
C.
F.
Step-by-step explanation:
If you use a graphing calculator on desmos.com, it is very easy to find the answer.
Area =legnth times width
square=legnth times legnth
2.54 is the legnth
area=2.54 times 2.54=6.4516 cm^2
so a square inch does not equal 2.54 cm^2
