The number of problems that were on the text was 240 problems.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let x represent the total number of problems that were on the text, y represent the time to be spent, hence:
y = x/8
Also:
y - 6 = x/10
x/8 - 6 = x/10
x = 240
The number of problems that were on the text was 240 problems.

33.
Explanation:
Since 2×22=44, if you do 1.5×22, you get 33.
Answer:
Answer:
Option C.
Step-by-step explanation:
The vertex form of a parabola is
where, a is constant, (h,k) is vertex.
If a<0, then it is a downward parabola and if a>0, then it is an upward parabola.
A downward parabola never lies entirely above the x-axis.
First equation is
It is a downward parabola and vertex is (-7,7).
Second equation is
It is an upward parabola and vertex is (7,-7).
Third equation is
It is an upward parabola and vertex is (7,7).
Fourth equation is
It is a linear equation with y-intercept -7.
Only equation 3 is an upward parabola whose vertex lies above the x-axis.
Answer:
y=32
Step-by-step explanation:
y=3(8)+8
y=24+8
24+8=32
y=32
Answer:
y + 1 + y + 2 + y + 3 =3y+6
