Answer:
x = 5
Step-by-step explanation:
x + 14 = 19
x + 14 - 14 = 19 - 14
x = 5
Answer:
C
Step-by-step explanation:
substitute X=7 in 2x+8, answer 22
substitute X=5, answer 18
option C
substituting X=7 in (X+4)+(X+4) also gives 22
substituting X=5 also gives 18
Answer:
Step-by-step explanation:
Lesson : GCF
Let us start on the numerical terms:
Common factors for all these numbers are 1 , 2 , and 4,
Since we are looking for GCF, 4 is the term for numerical GCF.
Now for the variable terms:
Common factors for all these numbers are x
Therefore x is the term for variable GCF
Eay peasy
solve graphically
graph them and find the poitn that they intersect at
y=mx+b
m=slope
b= y intercept
y=7x-9
slope=7
yintercept=-9
y=3x-1
slope=3
yinercept=-1
I have attached graph below
easier way would be to simply sub them and solve
7x-9=y=3x-1
7x-9=3x-1
4x-9=-1
4x=8
x=2
y=3x-1
y=3*2-1
y=6-1
y=5
(2,5) is solution
x + 20 = 44
x = 40 - 22
x = 18
Your answer: 18 square inches.
Hope this helps!
