D. (4,3). This is since the solution must be in the x shade, which is the pinkish part of the graph and d is the only answer I see
Answer:
y=1
x=-7
Step-by-step explanation:
x+y=-6 x=-6-y
x+5y=-2
substitute
(-6-y)+5y=-2
reduce
-6+4y=-2
4y=4
y=1
x=-6-y=-6-1=-7
Answer:
answer is B) 87.5 squared inches.
Step-by-step explanation:
The original dimensions of the photograph were 5 inches by 7 inches so, the area of the original photograph can be computed as the area of a rectangle:
.
So
![Area=(5)(7)](https://tex.z-dn.net/?f=Area%3D%285%29%287%29)
squared inches.
Now, for computing the area of a photograph of 250% the size of the original we use a simple rule of three:
35 squared inches -------- 100%
X squared inches --------- 250%
By this, we have:
![X = \frac{(35)(250)}{100}](https://tex.z-dn.net/?f=X%20%3D%20%5Cfrac%7B%2835%29%28250%29%7D%7B100%7D)
![X = 2.5*35](https://tex.z-dn.net/?f=X%20%3D%202.5%2A35)
![X = 87.5](https://tex.z-dn.net/?f=X%20%3D%2087.5)
Answer:the answer is 7
Step-by-step explanation:
1) multiply 3 * 7 which is 21
2) multiply 2 * 7 which is 14
3) subtract 14 from 21
4) and you got 7
So you have 7 more red bouncy balls
Answer:
The Inequality describing the situation is
.
Step-by-step explanation:
Let the number of laps he runs be !['r'](https://tex.z-dn.net/?f=%27r%27)
Let the number of laps he swims be !['s'](https://tex.z-dn.net/?f=%27s%27)
Now Given:
Time required to run each lap = 3 min
Time required to swim each lap = 2 min
Total minutes he need to exercise more than 45
we need to write the Inequality representing the same.
Solution:
Now we can say that;
Time required to run each lap multiplied by the number of laps he runs plus Time required to swim each lap multiplied by the number of laps he swims should be greater than Total minutes he need to exercise.
framing in equation form we get;
![3r+2s>45](https://tex.z-dn.net/?f=3r%2B2s%3E45)
Hence The Inequality describing the situation is
.
