1. -3 2/5 + b = 8 1/52. -7/3 n = -42PLZ HELP ASAP I WILL MARK BRAINLIEST

1 answer:

7 0

1. Convert the mixed numbers into improper numbers (-3 2/5 = -17/5 and 8 1/5 = 41/5). Then add 17/5 to both sides when means b=58/5

2. Multiply both sides by the reciprocal of -7/3 (which is -3/7). So n=18

Find the m ∠YXZ. Show your Work

Charra [1.4K]

Answer:

∠YXZ = 62°

Step-by-step explanation:

A straight line measures 180 degrees

The angle "8x - 14" PLUS its adjacent angle Z sum up to 180, so we can write:

Z + 8x - 14 = 180

Z = 180 +14 - 8x

Z = 194 - 8x

Sum of 3 angles of a triangle is 180 degrees, thus we can write:

X + Y + Z = 180

3x + 5 + 4x + 194 - 8x = 180

Now, we solve for x:

$3x + 5 + 4x + 194 - 8x = 180\\-x+199=180\\x = 199-180\\x=19$

The measure of ∠YXZ is "3x + 5", we substitute the value of x and find this angle to be:

3x + 5

3(19) + 5

Thus,

∠YXZ = 62°

What is a decimal as a eighth note

Vera_Pavlovna [14]

Idk,
Tips with decimals....

Our decimal system gives us the flexibility to write numbers as large or small as we like. The key to the decimal system is the decimal point. Anything on the left of the decimal point represents a whole number, anything on the right of the decimal represents less than one (similar to a fraction). Going from left to right, the value of each place on the right of the decimal point is 1/10 the value of the place on the left. Good luck!
