Answer:
I think there is a missing “and” there: “If the sum of the square of the number and 4 times the number is 21, what is the number?”
If so, then we have: x² + 4x = 21, or x² + 4x - 21 = 0.
This factors as (x+7)(x-3) = 0, so x = -7 or x = 3.
simplify and solve ( use the 4 step of solving )
Answer:
-(3-y)+2(y+8)=48y-16/-16
y=−2

Yesterday, Grace drove 36 1/2 miles. She used 1 1/4 gallons of gasoline. What is the unit rate for miles per gallon? The unit roto is miles per gallon?
Answer:
29.2 miles/gallon
Step-by-step explanation:
Given that,
Distance travelled, [tex]d=36\dfrac{1}{2}[/tex] miles
Grace used [tex]1\dfrac{1}{4}\ \text{gallons}[/tex] of gasoline
We need to find the unit rate for miles per gallon. It can be calculated by dividing no of miles by gallons of gasoline. So,
[tex]R=\dfrac{36\dfrac{1}{2}\ \text{miles}}{1\dfrac{1}{4}\ \text{gallon}}\\R=\dfrac{\dfrac{73}{2}}{\dfrac{5}{4}}\ \text{miles per gallon}\\\\R=\dfrac{73}{2}\times \dfrac{4}{5}\\\\R=29.2\ \text{miles per gallon}[/tex]
Hence, the unit rate is 29.2 miles/gallon.
Alligator 1 initial weight is 4 lbs. the rate of growth is 2 lbs. per month. Alligator 2 initial weight is 8 lbs. the rate of growth is 1 lb per month. After how many months will both alligators weigh the same amount?
Answer:
4 months.
Step-by-step explanation:
So I added this "out" and the LCM (Least Common Multiple) is 12. So it'd take 4 months for both of them to hit 12 pounds.

if the average of 2 and p is equal to the average of 1,6, and p, what is the value of p
Answer:
p = 8
Step-by-step explanation:
[tex]\frac{2+p}{2}=\frac{1+6+p}{3}\\\\\frac{2+p}{2}=\frac{7+p}{3}\\\\[/tex]
Cross multiply
(2+p) * 3 = (7 + p) * 2 {Use distributive rule}
2*3 + p*3 = 7*2 + p *2
6+ 3p = 14 + 2p {subtract 2p form both sides}
6 + 3p - 2p= 14
6 + p = 14 {Subtract 6 form both sides}
p = 14 - 6
p = 8
If the perimeter of the pink rectangle is 24 meters, what are its dimensions?
Answer:
You know the perimeter is 24 meters. this means that 24 is equal to 14 plus 2 times the width. since the perimeter is equal to 2 times the length plus 2 times the width, if you take away 2 times the length, you are left with 2 times the width. perimeter is equal to 24.

At 324 inches, the green anaconda is longer than Medusa (302 inches). C. Medusa (302 inches) is longer than the green anaconda (270 inches). D. At 333 inches, the green anaconda is longer than Medusa (302 inches).
Answer:
D. At 333 inches, the green anaconda is longer than Medusa (302 inches).

Medusa is a python who lives in captivity. She measures 302 inches in length. A green anaconda was measured at 27 feet 9 inches long.
Step 1
let each snake have their Length having the same units which is inches
Medusa = 302 inches
Green Anaconda = 27 feet 9 inches long.
1 foot = 12 inches
27 feet =
= 27 × 12 = 324 inches
Green Anaconda =( 324 + 9) inches
= 333 inches
Therefore, the Green Anaconda (333 inches) is longer than the Medusa(302 inches)
