Answer:
In the explanation
Step-by-step explanation:
a) Multiply the second equation by 2, subtract both lines. You get x = -3. Plug this in to get y, y = -2
b) Multiply the first equation by 2, add both lines. You get x = 8. Plug this in to get y, y = -3
c) Multiply the first equation by 5, subtract both lines. You get y = 1. Plug this in to get x, x = -3
d) Multiply the first equation by 2 and the second one by 3, add both lines. You get x = 1. Plug this in to get y, y = 4
Hope this helps!
2 1/8 + 1 3/4
3/4 = 6/8
1/8 + 6/8 = 7/8
2 + 1 = 3
3 + 7/8 = 3 7/8
There is a total of 3 7/8 cups of flour.
Answer:
Step-by-step explanation:
is our fraction, which is not in lowest form, and therefore can be reduced. We can divide both numerator and denominator by 2, and we end up with
7 goes into 14 twice, so we can reduce it further to become
To convert a fraction to a ratio, you just need to turn it on its side and make the | into a : So it would look like this:
1:21 / 2 = 0.5
<span>
0.5 is the fraction in decimal formTo find a percentage, you just need to multiply the decimal by 100.
0.5 in percentage form would be 50%
Hope that helped =)

Perimeter is the addition of all the sides
x-2+x+3x+1=2x-5+x+4+6x-7; since their perimeters are equal
5x-1=9x-8
collect the like terms
-1+8=9x-5x
7=4x
x=7/4
x=1.75
