Solve for b.
-3b+2.5 = 4

b = −0.5

Step-by-step explanation:

Let's solve your equation step-by-step.

−3b+2.5=4

Step 1: Subtract 2.5 from both sides.

−3b+2.5−2.5=4−2.5

−3b=1.5

Step 2: Divide both sides by -3.

-3b/-3 = 1.5/-3

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.
