Javier wants to buy a new video game that costs $62. Last week he saved $20 for the
game. If he earns $9 per hour at his part-time job, which equation can be used to find the
number of hours, h, Javier needs to work to have enough money to buy the video game?
Answer: 9h + 20 = 62
Step-by-step explanation:
he has 20 dollars now he needs 42 more so 9h is how much he earns multiplied by h how many hours he needs to work and you would add 20 onto that for the money he already saved and set that equal to the amount he needs
Sophia earns $9 an hour at a Mort's Pizza Palace, working 20 hours per week.
How many hours must Sophia work to buy a new phone that costs $150?*
A. 10
B. 17
C. 20
D. 150
Answer: 17 hours
Step-by-step explanation: she needs 150, she spends 3 and she makes 9 per hour
153/9 = 17
Answer:
17 hours
Step-by-step explanation:
10 x 9 = $90 No
17 x 9 = $153 Yes
20 x 9 = $180 No
150 x 9 = $1,350 No

The perimeter of a rectangular garden is 338 m.
If the width of the garden is 74 m, what is its length?
Answer:
l=95
Step-by-step explanation:
Perimeter is all the sides add up. So the equation if you know two of the sides, it should be: 338=(2*74)+(2*l)
Answer:
Step-by-step explanation:
the perimeter is 2w plus 2l
so 338 = 74(2)+2l
338 = 148+2l
190=2l
l=95
your length would be 95 m
(-5,-7) and (3,1)
write equation in point slope form, intercept form, and standard form
Answer:
Please check the explanation
Step-by-step explanation:
Given the points
(-5,-7) (3,1)Determining the slope between the points:
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-5,\:-7\right),\:\left(x_2,\:y_2\right)=\left(3,\:1\right)[/tex]
[tex]m=\frac{1-\left(-7\right)}{3-\left(-5\right)}[/tex]
[tex]m=1[/tex]
Writing the equation in point-slope form
As the point-slope form of the line equation is defined by
[tex]y-y_1=m\left(x-x_1\right)[/tex]
Putting the point [tex](-5,-7)[/tex] and the slope [tex]m = 1[/tex] in the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-7\right)=1\left(x-\left(-5\right)\right)\\[/tex]
Hence, the equation in the point-slope form will be:
[tex]y-\left(-7\right)=1\left(x-\left(-5\right)\right)[/tex]
Writing the equation in slope-intercept form
As the point-slope of the equation is
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
Putting m = 1 and (3, 1) to determine the y-intercept
[tex]y = mx+b[/tex]
[tex]1 = 1 (3) + b[/tex]
[tex]1 = 3 + b[/tex]
[tex]b = -2[/tex]
so putting [tex]b=-2[/tex] and m = 1 in the slope-intercept form
[tex]y = mx+b[/tex]
[tex]y = (1)x + (-2)[/tex]
Therefore, the equation in slope-intercept form is:
[tex]y = x -2[/tex]
Writing the equation in the standard form form
As we know that the equation in the standard form is
[tex]Ax+By=C[/tex]
where x and y are variables and A, B and C are constants
As we already know the equation in slope-intercept form
[tex]y = (1)x + (-2)[/tex]
so just simplify the equation to write in standard form
[tex]y = (1)x + (-2)[/tex]
[tex]y = x - 2[/tex]
[tex]y - x = -2[/tex]

The soccer team is making a circle graph to keep track of this year's games. So far, they have entered the data you see. How many games have they played this year?
1) 15 games
2) 25 games
3) 20 games
4) 5 games
Answer:
20
Step-by-step explanation:
this is divided into 4 pieces and only 3/4 of them are wins. If it is 15 games that are won we have to divide 3 and 15 which is 5 so you just add 5 to 15. Ps im sorry if u didnt understand to well im not the best at explaining.

Answer:
[tex]50^{\circ}[/tex]
Step-by-step explanation:
Complementary angles mean that the sum of the angles add up to [tex]90^{\circ}[/tex]. We can use algebra to solve for [tex]x[/tex] and then to determine [tex]m\angle QRS[/tex].
[tex]m\angle QRS + m\angle SRT = 90[/tex]
[tex]8x+10 + 8x = 90[/tex]
[tex]16x = 80[/tex]
[tex]x = 5[/tex]
[tex]m\angle QRS = 8x+10[/tex]
[tex]= 8(5)+10[/tex] (substitution)
[tex]=50^{\circ}[/tex]
∴ [tex]m\angle QRS = 50^{\circ}[/tex]

A red cross helicopter takes off from headquarters and flies 120 km at 45 degrees south of west. There it drops off some relief supplies, then flies 125 km at 20 degrees west of north to pick up three medics. If the helicoper then heads directly back to headquarters, find the distance and direction it should fly.
Answer:
129.5km
9.78° North of east
Step-by-step explanation:
Let say HQ is at the origin (x = 0, y = 0)
the coordinates of the helicopter after the 1st flight can be expressed below as
X1= -120 cos45=84.85km
Y1= -120 sin45= -84.85km
its coordinate after the 2nd flight can be expressed as
X2= x1 - 125sin20
= -84.85-42.75
=-127.6km
Y2= y1- 125cos60
=-84.5+62.5
=-22km
The distance and it's direction for it to fly back to its HQ can be calculated as
S= √(22^2 + 127.6^2 )
=129.48km
Tan θ= y2/y1
=22/127.6= 0.1724
Tan-1(0.1724)
= 9.78° North of east
Hence, the distance and direction it should fly is 129.48km and 9.78° North of east respectively

What is the equation of the line that is parallel to the line y = x + 4 and passes through the point (6, 5)?
y = x + 3
y = x + 7
y = 3x – 13
y = 3x + 5
Answer:
L = x - 1
Step-by-step explanation:
Let the equation of the line we are trying to find be L.
Since L is parallel to y, they would have the same gradient
So: L = x + c
c is the constant or the y-intercept
Sub in the point (6 , 5)
5 = 6 + c
c = -1
∴ L = x - 1
What is an example of a rational number that is not an integer?
Answer:
2.5 is a rational number which is not an integer. A rational number is a number which can be written as a ratio of two whole numbers (integers). For example 5 is a rational number since 5 can be written as ratio of 5 : 1 . 5 is also an integer.
1/2 4/3 3/4 all of these are rational but not integers
If you were to roll the dice one time what is the probability it will NOT land on a 5?
Answer:
as a percent or certainty?
Answer:
There is a 5/6 chance the dice will not land on 5.
Step-by-step explanation:
There are six sides on the dice and 5 is one out of those six options so we simply eliminate that option subtracting one out of six over all options.

Answer:
6) round 287 to 300
3*300=900
7) round 1310 to 1000
6*1000=6000
8) round 62 to 60
9*60=540
(sorry i have to go i'll help w/ the rest later!)
Answer:
6. you can round 287 to the nearest 10 which will be 290 so 290 times 3 equals 870
7. round 1,310 to the nearest 100th which is 1,300 so 1,300 times 6 equals 7,800
8. round 62 to the nearest 10th which equals 60 then 60 times 9 equals 540
Step-by-step explanation:
9. round 486 to the nearest 10th which is 490 so 490 times 7 equals 3430 then mark unreasonable
10. round 1,240 to the nearest 100 which will be 1,200 so then 1,200 times 5 equals 6,000 then mark unreasonable
11. round 287 to the nearest tenth which is 290 so then 290 times 5 equals 2610
