This is a system of linear equations. First, you can add the two equations together to eliminate the y so that you can solve for x:
-5x + -7x = 0 + -96
-12x = -96
x = 8
Use x to solve for y:
-5 * 8 + 8y = 0
Add 40 to both sides and divide by 8:
y = 5
So, x = 8 and y = 5.
Make a ratio, then cross multiply.
4/30=x/48
30x=4x48
30x=192
x=6.4
98 degrees.
30+52=82
180-82=98
answer:
18 m
step-by-step explanation:
- simply add up all the numbers given
- 1.7 + 3.7 + 3.7 + 3 + 5.9 = 18
- then, put the units given
Answer:
x = 49
Step-by-step explanation:
- Write it out as an equation: 3x + 33 = 180
- Subtract 33 from each side, so it now looks like this: 3x = 147
- Divide each side by 3 to cancel out the 3 next to x. It should now look like this: x = 49
I hope this helps!
