Answer:
C.
Step-by-step explanation:
C. is correct bc it makes the most sense out of all of them just check my work by dividing by 2.
Median is just the middle number. If you put all the numbers in order from least to greatest:
4,5,6,7,8,9,10
Then you can find the one in the middle. In this case it’s 7.
B. The solution is 5 times as small as 980+205
Answer:
61°
Step-by-step explanation:
We have many angles and are asked to find angle number 4.
Looking at the picture, if we take a look at the angle across (mirrored) from 4, we see that it lists being 61 degrees, since that angle is a complete mirror of angle 4. Angle number 4 is 61°
23) x =
= -6.666.
24) x =
= -1.7142.
25) x =
= -7.4.
Step-by-step explanation:
Step 1; For
=
, we cross multiply the denominators and get,
3 × (x + 4) = 12 × (x + 6),
3x + 12 = 12x + 72.
We take all the x terms to the LHS and keep the constants on the RHS.
3x - 12x = 72 - 12,
-9x = 60, x =
= -6.6666.
Step 2; For
=
, we cross multiply the denominators and get,
-5 × (x + 12) = 9 × (x - 4),
-5x - 60 = 9x - 36.
We take all the x terms to the LHS and keep the constants on the RHS.
-5x - 9x = -36 + 60,
-14x = 24, x =
= -1.7142.
Step 3; For
=
, we cross multiply the denominators and get,
6 × (x - 8) = 11 × (x - 1),
6x - 48 = 11x - 11.
We take all the x terms to the LHS and keep the constants on the RHS.
6x - 11x = -11 + 48,
-5x = 37, x =
= -7.4.
