She began with 20.
If she bought 7 more books and ended up with 17, that means she had ten beforehand. If she had half remaining, we simply double it, thus getting 20.

Answer:
4.2 cm
Step-by-step explanation:
Given
Area of parallelogram (A) = 4.2 cm²
base (b) = 1.75 cm
Height (h) = ?
We know
A = b * h
4.2 = 1.75 * h
h = 4.2 / 1.75
H = 2.4 cm

h < -20w+6=2(w-6) what is the answer?
Answer:
w = 18
Step-by-step explanation:
w+6 = 2(w-6)
w+6 = 2w-12
2w-w = 6+12
w = 18
hope it helps
Answer:
[tex] \huge \boxed {w = 18}[/tex]
Step-by-step explanation:
Distribute 2 in the bracket.
[tex]w + 6 = 2w - 12[/tex]
A constant and variable cannot add up or subtract each others. Therefore, move the same term to the same side.
[tex]12 + 6 = 2w - w \\ 18 = w[/tex]
Answer Check
Substitute w = 18 in the equation.
[tex]18 + 6 = 2(18) - 12 \\ 24 = 36 - 12 \\ 24 = 24[/tex]
Therefore w = 18 is the correct answer.

2) You traveled 210 miles in 3.5 hours.
How many miles will you travel per hour?
Answer:
= 56.7 miles per hour
Step-by-step explanation:
Step-by-step explanation:
To find the average speed for the entire journey, we need to find the entire distance and the total time
Entire distance = 210 miles + 130 miles = 340 miles
Total time = 3.5 hours and 2.5 hours = 6 hours
Average speed = distance/ time = 340 miles/ 6 hours
= 56.66666666666 miles per hour
Rounding to the nearest tenth
= 56.7 miles per hour
Answer:
60 miles
Step-by-step explanation:
Step 1:210=3.5
x =1
Step 2: cross multiply3.5×x= 210×1
3.5x=210
Step 3: divide both sides by the coefficient of x which is 3.53.5x/3.5=210/3.5
x=60
Answer= 60 miles

First nothing us negative, so multiply 8/4 times 9/3,which is 72/12=6, 6×12 is 72.The reason why it is 9/3 instead of 3/9 is because you are dividing so KCF, keep change flip.
Answer:
Positive 6
Step-by-step explanation:
What you do is:
8 x 9 = 72

Taylor will order one t-shirt for each person who attends her family's reunion. The cost is
$8 per t-shirt plus a one-time printing fee of $40.00. This can be represented by the
equation c = 8n + 40, where c represents the total cost of the shirts and n represents
the number of shirts ordered. If the family can spend no more than $600.00 on t-shirts,
what is the maximum number they can order?
B) 75
C) 70
A) 80
D) 15
Answer:
C) 70
Step-by-step explanation:
Since they can only spend a maximum of $600, we can fill that in for c. Now, we can solve the equation for n.
600 = 8n + 40
~Subtract 40 to both sides
560 = 8n
~Divide 8 to both sides
70 = n

Answer:
x = 1.7
Step-by-step explanation:
Given
-½ + 5x = 8
Required
Find x
-½ + 5x = 8
Multiply both sides by 2
-1 + 10x = 16
Collect like terms
10x = 16 + 1
10x = 17
Divide both sides by 10
x = 1.7

2. in a class of 50 students, the number of females is 2 more than 5 times the number of males. How many males and females are there in the class?
Answer:
There are 8 males in the class and 42 females.
Step-by-step explanation:
This question can be solved using a system of equations.
I am going to say that:
x is the number of females.
y is the number of males.
Class of 50 students
This means that [tex]x + y = 50[/tex]
The number of females is 2 more than 5 times the number of males.
This means that [tex]x = 5y + 2[/tex]
So, finding y, the number of males:
[tex]x + y = 50[/tex]
[tex]5y + 2 + y = 50[/tex]
[tex]6y = 48[/tex]
[tex]y = \frac{48}{6}[/tex]
[tex]y = 8[/tex]
Females:
[tex]x = 5y + 2 = 5*8 + 2 = 42[/tex]
There are 8 males in the class and 42 females.
