Answer: AB is 40

Step-by-step explanation: CD=CE+ED ED is 5 and it is also the midpoint meaning it is 1/2 of the value of the line. Therefore CD is 10, BC=BD+CD CD as we know is 10 and D is the mid point meaning it is also 1/2 of the value of BC. 10+10=20, AB=AC+BC, BC is 20 so AC must also be 20;therefore AB is 40

The answer is C., $24 per month.

Answer:

A $12

Step-by-step explanation:

she has saved $36 before she gets a part time job, after 2 months, her savings have increased from 36 to 60. 2 months = 60 - 36, 2 months = 24. now we divide 24 by 2, and the answer is 12. option A is correct.

Answer:

a. [tex]Savings = \$16[/tex]

b. [tex]Price = \$96[/tex]

Step-by-step explanation:

Solving (a):

[tex]Price = \$80[/tex]

[tex]Coupon = 20\%[/tex]

Required

Determine her savings.

[tex]Savings = Coupon * Price[/tex]

[tex]Savings = 20\% * \$80[/tex]

[tex]Savings = \$16[/tex]

Solving (a):

[tex]Price = \$120[/tex]

[tex]Coupon = 20\%[/tex]

Required

Determine the price before tax

First, we need to determine her savings

[tex]Savings = Coupon * Price[/tex]

[tex]Savings = 20\% * \$120[/tex]

[tex]Savings = \$24[/tex]

The price before tax is calculated as follows:

[tex]Price = \$120 - \$24[/tex]

[tex]Price = \$96[/tex]

Answer:

The numbers 4, 9, 25, and 49 are composite numbers.

The number 1 is a prime number.

Step-by-step explanation:

A prime number can be defined as a number that is divisible by 1 and itself only. Examples are: 1, 3, 5, 7, 11 e.t.c

A composite number can be defined as a positive number that can be formed by multiplying two smaller positive numbers together. These two positive integers may or may not be prime number.

It is a positive integer that has at least one divisor other than 1 and itself.

Examples are: 4, 6, 8, 9, 12, 25, 49, e.t.c

Therefore, the true statements in the questions above =

The numbers 4, 9, 25, and 49 are composite numbers.

Answer:

There will be 2 bags of chips sold

Step-by-step explanation:

A system of equation is a collection of one or more equation involving the same variables.

Now , according to question :

since , he had sold 26 lollipop , then total money he made from lollipop is : 26 * $1 = $26

Let us assume he sold x number of chips

money made from chips = $ 1.50 * x

Total money made : $30                          (Given )

equation according to question will be

26 + 1.50 x = 30

x= 2.7

Since , number of packets  can never be in decimal hence, rounding off to 2 packets

x= 2

Answer:

Step-by-step explanation:

Answer:

2 1/2

Step-by-step explanation:

−45+3310=?

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(-4/5, 33/10) = 10

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(−45×22)+(33/10×11)=?

Complete the multiplication and the equation becomes

−8/10+33/10=?

The two fractions now have like denominators so you can add the numerators.

Then:

−8+33/10=25/10

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 25 and 10 using

GCF(25,10) = 5

25÷5/10÷5=5/2

The fraction

52

is the same as

5÷2

Convert to a mixed number using

long division for 5 ÷ 2 = 2R1, so

52=212

Therefore:

−4/5+33/10= 2 1/2
