Answer:
jack (with the lower case j) is 11 years old
Step-by-step explanation:
(x - 5) + (3x - 5) = 34
x - 5 + 3x - 5 = 34
4x = 34 + 10
4x = 44
x = 11
So, jack = 11 years old.
Jack = 33 years old.
Answer: X = 57.5
Step-by-step explanation:
3x - 65 + x + 15 = 180
4x - 50 = 180
4x = 230
x = 57.5
Step-by-step explanation:
A ratio is a relation between two numbers.
*A ratio determines how many times 20 contains/values 8.
<u>A ratio representing the width to the length is: </u>
8:20.
8 represents the width, 20 represents the length.
To simplify a ratio, you must divide each side by the same number.
<u>S</u><u>i</u><u>mplified </u><u>ratios</u><u> </u><u>are</u><u>:</u>
4:10 (Divide by 2)
2:5 (Divide by 4)
1:2.5 (Divide by 8)
The ratio is detailing that the length is 2.5 times larger than the width.
<u>Your answers are;</u>
8:20
4:10
2:5
1:2.5
Answer:
Time, t = 4.5 s
Step-by-step explanation:
The number of seconds t it takes the ball to hit the green can be represented by the equation :
It means that the initial velocity is 70 ft/s. The above equation becomes:
It is required to find the time taken by the ball to land on the ground. It is a quadratic equation. The solution of quadratic equation is given by :
t = −0.125 and t = 4.5 s
Time cannot be negative. So, the time taken by the ball to land on the ground is 4.5 seconds.
Answer:
(a) (-1, -5)
Step-by-step explanation:
An ordered pair is a solution to an equation when using those x and y values makes the equation true. Here, the equation tells you the y-value is 4 less than the x-value. Of the choices offered, that is only true for ...
(x, y) = (-1, -5)
