he needs to get a 91 to have a mean score of 90

Step-by-step explanation:

add up all the known scores to get 629

let 's' = lowest test score

(629 + s) ÷ 8 = 90   [we divide by 8 because there are 7 known and 1 unknown score)

cross-multiply to get:

629 + s = 720

s = 720-629

s = 91

Select all the true statements. Triangle A B C where the measure of angle A is 2 x plus 1 degree, angle B is x degrees, and angl
Step2247 [10]

Answer:

B= 41; C  = 56; A = 83

Step-by-step explanation:

Given

A = 2x + 1

B = x

C = x + 15

Required

Arrange the angles from smallest to largest

First, we need to determine the value of x.

Since, it is a triangle:

A + B + C = 180

Substitute values for A, B and C

2x + 1+ x + x + 15 = 180

Collect Like Terms

2x + x + x = 180 - 15 -1

4x = 164

Solve for x

x= 164/4

x= 41

Solve for A, B and C

A = 2x + 1

A = 2 * 41 + 1

A = 82 + 1

A = 83

B = x

B= 41

C = x + 15

C  = 41 + 15

C  = 56

From Smallest to Largest, we have:

B= 41; C  = 56; A = 83
