Answer:
B
Step-by-step explanation:
The given equations satisfy the given conditions. There are 2 equations and 2 unknowns, so a certain solution can be found.
This can be solved using substitution,
Substituting eqn 2 to eqn 1:
2(2y – 10) + 3y =1240
Simplifying,
y = 180
x = 350
Answer:
No Solution
Step-by-step explanation:
8x+2y=13 4x+y=11 Subtract 4x on both sides to isolate y
y=-4x+11 <---- Substitute this equation into the
equation 8x+2y=13
8x+2(-4x+11)=13
8x-8x+22=13
22=13 (not true)
No Solution
Answer:
From this, you can tell it's in slope-intercept form, has a slope of -1/2, and a y-intercept of -4.
I've included a picture of what this equation looks like.
1,000,000 times 100 equals 100,000,000
Ok, this looks a lot harder than it is. Either way, a calculator/computer can work miracles. Have a good day!!
I'm not sure what you do with the whole numbers but 0.8 is 80% and 82% is higher than 80% so its not 0.8
