Hello!
You have to find what a and b are
3a + 4a = 14
b + 6b = 21
Lets do a first
3a + 4a = 14
Combine like terms
7a = 14
Divide both sides by 7
a = 2
Now lets do b
b + 6b = 21
Combine like terms
7b = 21
Divide both sides by 7
b = 3
Put a and b into the third equation
7( 2 + 3) =
Do what is in parenthesis first
7(5) =
Multiply
35
The answer is 35
Hope this helps!
Answer:
look it up its the same as the equation
Step-by-step explanation:
Answer:
Option F. 
Step-by-step explanation:
we know that
The solution of the inequality of the graph is the shaded area above the solid line
step 1
Find the equation of the solid line
The intercepts are
The y-intercept is the point (0,b)
The x-intercept is the point (-b,0)
Find the slope
The equation of the solid line is
step 2
The solution of the inequality is the shaded area above the solid line
therefore
the inequality is equal to
Answer:
Width equals 11, and length equals 12.
Step-by-step explanation: It is helpful to memorize your multiplication tables up to 12. I personally couldn't figure out a formula for this, but I knew that 12 x 11 equals 132, and the length is greater than the width, so length is 12 and width is 11. Hopefully somebody else can figure it out. P.S. I meant the formula, not the answer, my answer is correct.
8 yards is equal to 288 inches.
1 yard=36 inches
36x8=288
288 converted to yards=8
