70% of 100 is 70 students.
Unfortunately I can not make a model for you but here's an idea:
Draw a large circle.
Next, draw a line halfway down the circle, and halfwar down draw another line to the right, this making it look like three fourths.
Then, color the larger space in one color and the other smaller space that looks like a small slice of pie in another color.
On the larger piece write "70% who got an A" and on the smaller write "30% who didn't get an A"
At the bottom you can write 70 students out of 100 got an A on the test.
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 8 and c = - 5, thus
y = 8x - 5 → B

Answer:
- garden: 8 years
- tree: 120 years
Step-by-step explanation:
Let g represent the age of the garden. Then the age of the tree is 15g. The sum of their ages is ...
g +15g = 128
16g = 128 . . . . . collect terms
g = 128/16 = 8 . . . . divide by the coefficient of g
The garden is 8 years old; the tree is 120 years old.
