Which shows the correct solution of the equation
50, when b=30?
3a + 301=50
Žo+20=50
Ź a +20 - 20 =50-20
{a=30
2(a)=(30)
a =15
To+ 100)=50
20+20=50
+20+20=50+20

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
