What you need to do is to find a multiple of 20 and 16 in other words a number that can multiply into 20 and 16. You have 2 and you have 4. So now this is how it looks like.
Either:
4(5+4) Or
2(10+8)

First, I would find that the GCF of 20 and 16 is 4. Then, I would divide both 20 and 16 by 4. Last, I would use the distributive property to write the sum as 4(5 + 4).

The width of a rectangle is 7t-1.5 feet and the length is 1.5t + 8 feet. Find the perimeter of the

Tasya [4]

Step-by-step explanation:

✧ $\underline{ \underline{ \large{ \tt{ \: G \: I\:V \: E \: N}}}} :$

Width of a rectangle ( w ) = 7t - 1.5 ft
Length of a rectangle ( l ) = 1.5t + 8 ft

✧ $\underline{ \underline{ \large{ \tt{ \: T \: O\: F\: I \: N \: D}}}} :$

Perimeter of the rectangle

✧ $\underline{ \underline{ \large{ \tt{S \: O \: L \: U \: T \: I\: O \: N}}}} :$

❀ $\boxed{ \large{ \text{Perimeter \: of \: a \: rectangle \: = \: 2(l + w)}}}$

⟶ $\large{ \tt{2(1.5 \: t \: + 8 \: + 7t - 1.5}})$

⟶ $\large{ \tt{2(1.5t + 7t + 8 - 1.5)}}$

⟶ $\large{ \tt{2}(8.5t + 6.5)}$

⟶ $\large{ \tt{17t + 13}}$

☄ $\underline{ \boxed{ \boxed{ \tt{Our \: final \: answer : \underline{ \boxed{17t + 13 feet}}}}}}$

You have a mean score of 84 after taking five 100-point tests. What do you need to score on the sixth 100-point test to have a m

kap26 [50]

The mean of n numbers is the sum of the numbers divided by n.

You have a mean score of 84 after taking 5 tests. Let x be the sum of scores.
$\frac{x}{5}=84 \\
x=84 \times 5 \\
x=420$
You scored a total of 420 points on five tests.

You need to have a mean score of 85 after taking 6 tests. Let y be the score you need to obtain. Your total score on 6 tests is 420+y.
$\frac{420+y}{6}=85 \\
420+y=85 \times 6 \\
420+y=510 \\
y=510-420 \\
y=90$

You need to score 90 points on the sixth test.
