Erin had $35 more than Angie who had 3 times as much money as Jacob. If they had $196 altogether, how much money did each have?
Answer:
$23
Step-by-step explanation:
let j be jacob"s money
Then angie is 3j, and Erin is 3j+35 so 7I
=161
j=23
Answer: Erin - $104; Angie - $69; Jacob - $23.
(please give me brainlest ❤️)
Step-by-step explanation:
JACOB has least amount of money, so let's say that he has :
x amount of money
ANGIE has 3 times more than jacob:
Angie has 3x
ERIN has $35 more money than Angie:
3x+35
their money together is $196, that means if we add all of their money, it will be equivalent of 196:
3x+35+3x+x=196
now lets find x value.
put all the xes on right side and all known numbers on left side.
i think u know that when it goes to another side it changes sign; for example - makes + and × makes /
3x+35+3x+x=196
7x=161
x=161/7
x=23
now plug x values for each kid:
so Jacob had x=23
Angie had 3x=3×23=69
and Erin had 3x+35=69+35= 104
lets check our answer:
23+69+104=196
196=196
so sum of their money really gives us $196.

the first number is the x number which on the graph is the horizontal line and the second number is the y number which on the graph is vertical.
Theres also negatives which is the same thing but its on the lower side of the graph.
So now for example you take -4,-9.
To make it easy move the dot to the center or the (0,0) cords. Then follow the numbers. When you start on the zero cord you will look at the numbers, it says -4 so drag the dot 4 units to the left where the line says -4. Then drag it down 9 units so its on the cords. Hope this helps!!
Answer:
Ok so for (0,8 1/2), drag the dot from the middle, up to 8 but then move up a little bit more so it is between the 8 and 9. Next, for (-4, -9) drag one of the other dots to the -4 on the horizontal line, but then move it down to the -9 on the vertical line. And finally for (-6,5), you should put the last dot on the -6 on the horizontal line, but move it up five spaces until it is at the 5 on the vertical line.
I hope I was able to help you, if you still do not understand I will try to explain a little bit more.

Read the article below carefully and answer the question that follows.
On the morning of July 15, 2006, fourteen school buses were vandalized. The buses, property of Walt Whitman Middle School, were parked in the "bus barn" on campus. The vandals spray-painted the buses with pictures of dogs. Dogs happen to be the mascot of rival school Edgar Allan Poe Academy. This has led some to believe that some students from EAPA may be the culprits in the incident. Says the mother of one Walt Whitman student, "Oh, yeah, the [Edgar Allan] Poe [Academy] kids are definitely responsible. Those kids don't have any discipline, and they're still stewing over the loss of last week's football game." Police, however, say that they currently have no suspects.

Find the size of angle XYZ give your answer to 1 decimal place
Step-by-step explanation:
angle x=90°
xz=opposite
xy=adjacent
zy=hypotenuse
we neee to find acute angle
y°=(7/12)=0,58(3)
Applying the cosine ratio, CAH, the size of angle XYZ, to 1 decimal place is calculated as: 54.3°.
What is the Cosine Ratio?To solve a right triangle by relating the adjacent side to the hypotenuse, the cosine ratio is applied, which is: cos ∅ = adjacent/hypotenuse.
Given the parameters:
∅ = angle XYZHypotenuse = 12 cmAdjacent side = 7 cmApply the cosine ratio:
Cos (XYZ) = 7/12
Angle XYZ = cos^(-1)(7/12)
Angle XYZ = 54.3°
