Answer:
85
Step-by-step explanation:
complementary angles = 90* so 85+5=90
Answer:
85
Step-by-step explanation:
Complementary means those angles add up to 90
supplementary means those angles add up to 180
because on angle is 5 degrease and it says complementary you just...
90-5=x
85=x

Write and solve two division expressions that have a negative quotient. Use the fractions − 2 /3 , 5/ 6 , and − 1 4 . Show your work.
Answer:
By remembering a few simple rules, you will be able to divide any negative fraction problem you come across. Ignore the negative sign at first and multiply one fraction by the reciprocal of the other. The reciprocal is attained by simply flipping the numerator and the denominator.

Evaluate the expression 6x + 21y when Y = 4 x=3
Answer:
102
Step-by-step explanation:
You have to substitute x and y. Since x = 3 and y = 4, you would write the equation as 6(3) + 21(4). Multiply that, and you get 18 + 84. Add that together, and you get the answer 102.
Answer: 102
Step-by-step explanation: 6x + 2y
6(3) + 21(4)
18 + 84
102
basically you just plug in 4 where it says y in the equation and plug in 3 where it says x in the equation and solve :))

PLEASE HELP ME! ITS A TRICK QUESTION. IF ANYONE IS A MATH EXPERT, PLEASE HELP! I WILL MARK BRAINLIEST FOR THE BEST ANSWER.

Answer:
(4, -10), (4, 6)
Step-by-step explanation:
The vertical diameter is on the vertical line through the center of the circle. That line is x=4.
The square of the radius is 64, so the radius is √64 = 8. The y-coordinate of the diameter end points will be the y-coordinate of the center ±8.
So, the points of interest are ...
(4, -2±8) = (4, -10) and (4, 6) . . . . end points of the vertical diameter
Solve for h.
h/6 − 1 = −3
h =
Answer:
[tex]h = - 12[/tex]
Step-by-step explanation:
1) Add 1 to both sides.
[tex] \frac{h}{6} = - 3 + 1[/tex]
2) Simplify -3 + 1 to -2.
[tex] \frac{h}{6} = - 2[/tex]
3) Multiply both sides by 6.
[tex]h = - 2 \times 6[/tex]
4) Simplify 2 × 6 to 12.
[tex]h = - 12[/tex]
Therefor, the answer is h = -12.
Answer:
h = - 12
Step-by-step explanation:
Add 1 to both sides of the equation
ℎ/6 − 1 + 1 = − 3 + 1
Simplify
ℎ/6 = − 3 + 1
h/6 = -2
Multiply all terms by the same value to eliminate fraction denominators
6 ⋅ ℎ/6 = 6 ( − 2 )
Cancel multiplied terms that are in the denominator
ℎ = 6 ( − 2 )
Multiply the numbers
ℎ = − 12

Answer:
x = 5
y = 1/4
Step-by-step explanation:
Let a = 1/x
b = 1/y
Then the equations are
(1) 10a - 4b = -14 and (2) 5a + 8b = 33 Multiply equation (2) by -2
-10a - 16b = -66
-20b = - 80
b = 4 5a + 8(4) = 33
5a + 32 = 33
5a = 1
a = 1/5
a = 1/x = 1/(1/5) x = 5
b = 1/y = 4 y = 1/4
