Answer:
6
Step-by-step explanation:
So we have a number (let's call it x) and it was multiplied by 8 and added by 2. Therefore:
And we are told that the sum is equal to the product of 2 and 25 (or 50). Thus:
To find the number, we just need to find x. Thus, subtract 2 from both sides:
Divide both sides by 8:
And we're done!
So, our original number was 6.
Answer:
A - they are vertical angles so they are equal to each other
b - dont really know this one
c - y=24 and 7 and 8 = 89
Step-by-step explanation:
You messed up because the angles given are not supplementary the angles given that are next to 7 and 8 are vertical then we can setup an equation which would be 5y-29=3y+19 and solve for y
step 1 add 29 to each side
5y=3y+48
step 2 subtract each side by 3y
2y=48
step 3 divide each side by 2
y=24
then we plug in 24 to one of the expressions
5(24)=120
120-19=101
but we are not done yet because it is asking for the value of angle 7 and 8
because angle 7 is supplementary to both all we have to do is subtract 101 from 180
180-101=89 so 7 and 8 =89
hope this helps :D
Answer: 26
Step-by-step explanation: you divide 468 and 18 and you get 26.
Answer:
100
Step-by-step explanation:
it is C
sum means add +
-22.6667 ( or -22 2/3)
-4 * 5.6667 or -4 * 5 2/3 = -22.6667
