Age If you add Natalie's age and Fred's age, the result is 43. If you add Fred's age to 4 times
Natalie's age, the result is 79. Write and solve a system of equations to find how old Fred and
Natalie are.
Fred is
years old. Natalie is
years old.

Answers

Let’s take fred age as x and Natalie’s age as y.
So,
A/Q
X + Y = 43. Let it be eqution 1
and
X + 4Y = 79. Let it be equation 2

Combining equation 1 and 2, we get

( X + Y) + 3Y = 79
43 + 3Y = 79
3Y = 36
Y = 12

Now, evaluating the value of Y in equation 1 we get,

X + 12 = 43
X = 31

Therefore, Fred is 31years old and Natalie is 12 years old.

Use the distributive property to rewrite each expression in it's equivalent form 9a-3/3 ,Just 3 please

Answers

hahahah i think i already did this for you buttttt

the denominator can be distributed to both parts of 9a and -3

so you can rewrite it as (9a/3) and (-3/3)

to simplify (9a/3) is equal to 3a and (-3/3) is equal to -1

so the answer is 3a-1

Step-by-step explanation: got it right on edge

Since the sum of the angles in a quadrilateral is 360 degrees then the angle D is 50 degrees.

What is a quadrilateral?

A quadrilateral is a four sided figure. Examples of quadrilaterals include; square, parallelogram, rectangle, kite etc.

The sum of angles in a quadrilateral is 360 degree hence;

A + B + C + D = 360 (sum of angles in a quadrilateral)

128 + 126 + 54 + D = 360

D = 360 - ( 128 + 126 + 54)

D = 50 degrees

explain how you can use fractions strips or number lines to show that 3/4 and 6/8 are equivalent.

Answers

Answer:

answers is down there

Step-by-step explanation:

you can use fraction strips by using them 3/4 and 6/8 because they are equivalent and that's just life :)

3/4 and 6/8 are equivalent numbers/fractions

The fractions are given as:

[tex]\frac 34[/tex] and [tex]\frac 68[/tex]

To model 3/4 using number lines, we do the following steps

Draw a straight lineDivide into 4 equal segmentsPut a mark at the end of the 3rd point

To model 6/8 using number lines, we do the following steps

Draw a straight lineDivide into 6 equal segmentsPut a mark at the end of the 6th point

When both points are compared, then we find out that:

[tex]\frac 34 \equiv \frac 68[/tex]

Hence, 3/4 and 6/8 are equivalent

B- what will Sarah earn when the tips are $350? Explain your strategy

C- what were the nightly tips when Sarah earned $81? Explain your strategy

Thank you :]

Answers

Answer:

A: E = 0.05t +56

B: $73.50

C: $60.05

Step-by-step explanation:

A) I'll just explain the equation in one go

Equation: E = 0.05t + 56

0.05 - This is meant to represent the 5% of tips

5% = 5/100

5/100 = 0.05

56 - This is a set value that has been established as a constant, thus it simply needs to be added to the 5%

B+C) Since we already have the equation set up, we just need to plug in the variable, t.

B) E = 0.05(350) + 56

= 17.5 + 56

= 73.50

C) E = 0.05(81) + 56

= 4.05 + 56

= 60.05
