Diego has $10 and begins saving $2 each week toward buying a new phone. At the same time that Diego begins saving, Lin has $50 and begins spending $2 per week on supplies for her art class. Is there a week when they have the same amount of money?Write an equation and answer.

Answers

Answer:

no

Step-by-step explanation:

the easiest way to find out is to plot these on a graph

for Diego's function, we will write the total amount of savings (or his goal) = the amount hes saving multiplied by the weeks he saves + the amount he started with

y = 2x + 10 (in blue in attached file)

same with Lin

y = 2x + 50 (in red in attached file)

if the lines cross at any point, then that point on the two lines is the same value of x AND y, otherwise, one or the other is a different value

beings as these two lines have the same rate of change, they will not cross, meaning that neither will have the same amount if the rate continues

yes
on week 11 they will both have $30
please correct me if im wrong
because
10,12,14,16,18,20,22,24,26,28,30
50,48,46,44,42,40,38,36,34,32,30
it looks weird but if you count the number you will see that 30 is both on week 11

Answer: x=40 y=140

Step-by-step explanation:

To work out x:

The angles in a triangle always add up to 180.

You already have one angle which is 50 the bottom left angle is a right angle and right angles always equal 90. To work out x, do 50+90=140 then do 180-140=40.

To work out y:

Angles on a straight also add up to 180.

So as you have figured out what x is (40) you would take it away from 180 to give you y.

180-40=140

Hope this helps :)

A car travels 625.68 miles and uses 9.9 gallons of gas. What is the unit rate for gas?

Answers

Let’s make this into an expression then. Huh. A mile for a 16 thousandth of gas. You must have a pretty good car, dude.

Answer:

63.2:1

Step-by-step explanation:

We can find the unit rate by making equations that will help us solve.

We need to find how many miles the car travels in one gallon.

We can divide 625.68 by 9.9.

625.68/9.9 = 63.2

The car travels 63.2 miles on one gallon of gas.

Meaning that the unit rate is 63.2:1.
