Answer:
The answer is D.117
Step-by-step explanation:
Supplementary angles equal 180°.
180-63=117
Answer:
Step-by-step explanation:
Given
Required
Represent as an equation
The new position of the hook is calculated by:
This gives:
Hence, the equation is:
Answer is 2
Substitute each number into equation
4x = 8
4 (1) = 8. No
4 (2) = 8. Yes
4 (3) = 8. No
4 (4) = 8. No
1. 9/10 + 7/8 = 71/40 (or 1.775) so I'd say 2
2. 9/50 + 7/15 = 97/150 (or 0.64667...) so I'd say 1/2
3. is this 2/8 / 9 or 2 / 8/9 please let me know
4. is this 8/12 / 31 or 8 / 12/31 :)
5. is this 15/2 / 15 or 15 / 2/15
Please let me know the second halves of 3 through 5 as well! :)
Answer: Each blueberry pie costs $14 and each blackberry pie costs $18.
Step-by-step explanation:
If X is the price of a blueberry pie and Y is the price of a blackberry pie we have that:
3*X + 12*Y = $258
4*X + 3*Y = $110
We have a system of equations, to solve it first we can isolate one of the variables in one of the equations, let's isolate X in the first equation.
3*X = $258 - 12*Y
X = $258/3 - (12*Y)/3 = 86 - 4*Y
now we can replace it in the second equation and get:
4*(86 - 4*Y) + 3*Y = 110
344 - 16Y + 3Y = 110
344 - 13Y = 110
13Y = 344 - 110 = 234
Y = 234/13 = 18
So each blackberry pie costs $18.
And we can replace it in the equation for X and get the value of X.
X = 86 - 4*Y = 86 - 4*18 = 14
So the price of a blueberry pie is $14.
