2x-3=y and x-y=-4 rearrange both so that y is by itself on one side...
y=2x-3 and y=x+4 subtract second equation from first and you get:
0=x-7 add 7 to both sides...
x=7, now use this value for x in either original equation to solve for y...
y=2(7)-3, y=11 so the solution is the point:
(7,11)
Answer:
15 q4. + 7p2q2 is the correct answer
3 + 3 + 5 = 11 (11 total parts of the ratio.)
132 ÷ 11 = 12 (one part of the ratio)
Multiply 12 by the number of parts in the ratio:
12 × 3 = 36
12 × 3 = 36
12 × 5 = 60
Therefore, the final answer is 36:36:60 kg.
Answer:
x=71
Step-by-step explanation:
Since this is an isosceles triangle the bottom 2 angles are equal.
The three angles of the triangle are x, x, and 38. They must add to 180 degrees
x+x+38 = 180
Combine like terms
2x+38=180
Subtract 38 from each side
2x+38-38 = 180-38
2x = 142
Divide each side by 2
2x/2 =142/2
x =71
