Answer: Y = 4, X=4 (4,4)
Step-by-step explanation: You must multiply both equations so the leading coefficient cancels out. I’m multiplying both equations by both coefficients so I multiply the entire first equation by -2 so the first equation will be the negative coefficient and the second equation will be multiplied by positive 9 so the negative and positive equations cancel out.
STEPS IN MATH:
1. (9x-8y=4) -2 = -18x + 16y = -8
(2x-3y=-4)9 = 18x-27y= -36
2. ADD THESE EQUATIONS TOGETHER NOW
-18x+16y=-8
+ 18x-27y=-36
0-11y= -44
-11y=-44
DIVIDE -44 by -11y
The final answer is Y= 4
NOW pick an equation to plug in y to, any equation works
I chose the first one, so 9x-8(4)=4
9x-32=4
9x=36
x=4
Answer:
Scalene
Step-by-step explanation:
The reason is because all the sides are different.
Answer:
35 hot dogs and 52 sodas
Step-by-step explanation:
There are no choices so I’m going to assume this is simplification.
Answer:
3/4 —> this is the most simplified version of that fraction.
Explanation:
48/64 can be divided by multiple things to gain fractions. You could divide it by 2 repeatedly until arriving to a fraction wherein you couldn’t split anymore.
Ex.) 48/64 = 24/32 = 12/16 = 6/8 = 3/4
All of the above answers are equivalent to 48/64.
An easier way to reach the final answer of 3/4 would be to find the greatest common factor of 48/64. You can divide both by 16 and then get to 3/4.
Hope this helps!
