Answer:
16
Step-by-step explanation:
2c=c+16
C=16
To do this, we plug -1 in as x and -3 in as y. If the two sides are equal, (-1, -3) would satisfy y = x + -2. If they aren't equal, it doesn't satisfy the equation. We get:
-3 ? -1 + (-2);
and so,
-3 does indeed equal -3.
Thus, the point (-1, -3) satisfies the equation y = x + -2
Hello!
We know that mike can bind 109 flowers per hour.
Lets create an equation to remember this.
<u>Mikes equation: </u>
<u>109x = y</u>
<u />
<x is representing per hour in this math problem>
We know that John can bind 116 flowers per hour, here is his equation.
<u>Johns equation:</u>
<u>116x = y</u>
<u />
Question: If they work together for 5 hours, how many flowers can they bind?
First, plug in the number five in both equations.
Second, solve the equation by multiplying.
Mikes:
109(5) = y
109 times 5 is 545
y = 545
Johns:
116(5) = y
116 times 5 is 580
y = 580
We want to know how many flowers can they bind if they work together.
This means we need to add the answers of the equations from both mike's and john's together.
545 + 580 = 1,125
The answer is 1,125
Answer:
x=-1/3, y=3/4
Step-by-step explanation:
Isolate x
x=3-8y/9
Substitute x
6*3-8y/9-12y=-11
Simplify -52y+6/3=-11
Isolate y=3/4
Substitute y=3/4
x=3-8*3/4/9=-1/3
x=-1/3 y=3/4
Answer:
7
Step-by-step explanation:
As it is a RIGHT triangle, the formula is a^2+b^2=c^2.
We are given one leg and the hypotenuse. That means 4^2x2+b^2=81.
To find 4 root 2 square, you square them individually then multiply.
4^2=16 times 2 (root 2 squared is 2).
Simplified, that gives 16x2=32,
81-32=49.
The last leg is seven.
