Answer:
Step-by-step explanation:
The system is
x+y=60 and x-y=4
If we get the difference between the two equations above we get
x+y-x+y=60-4
2y=56
y=28
What is the equation of a line .........
Answer:
y = -x + 2, B is the answer
Step-by-step explanation:
If slope is -1, the equation is y = -x+b
Plug in (3,-1) into that equation.
-1 = -3 + b
b = 2
Write ways to represent the fraction 10/9.
Answer:
mixed number form 1 1/9
decimal form 1.11111111111111 it goes on forever

Step-by-step explanation:
i hope that helps!
Answer:
1 1/9
Step-by-step explanation:
10/9, you get 1 as the whole number.
You have a 1 left over when dividing 10 and 9. the 1 will be over 9.
Giving you 1 as the whole number and 1/9 next to it.

Answer:
2.4 cm
Step-by-step explanation:
We know the length of segment AB and the length of segment BC. To find their midpoints, we can divide their length by 2.
Let's find the midpoint of AB.
Segment AB: 10 cm Midpoint of AB: 10/2 = 5 cmNext let's find the midpoint of BC.
Segment BC: 5.2 cmMidpoint of BC: 5.2/2 = 2.6 cmIn order to find the difference between these midpoints, we can subtract the midpoint of AB by the midpoint of BC.
5 cm - 2.6 cm = 2.4 cmTherefore, the difference between the midpoints of AB and BC is 2.4 cm.

Step-by-step explanation:
A bag contains 5 red marbles, 6 blue marbles, 3 green marbles, 4 black marbles, and 2 yellow marbles. A marble will be drawn from the bag and replaced 100 times. What is a reasonable prediction for the number of times a green or black marble will be drawn?
A quick lesson on probability:
The probability of an event is: (the number of ways what you want can happen) / (total number of outcomes possible). For example, in a coin flip, there is 1 way to get heads, and 2 possible outcomes. Thus, the possiblity of flipping a coin and getting heads is:
(1 way to get heads) / (2 possible outcomes) = 1/2
Then, if we were to flip the coin 100 times, we would expect about 1/2 of the times to be heads, so we should expect heads 50 times.
On to the problem.
There are 3 green marbles and 4 black marbles, so there are 7 ways to draw a green or black marble.
Then, there are 5 + 6 + 3 + 4 + 2 = 20 possible outcomes.
Using the formula to find the probability, substitute the values we just found.
(the number of ways what you want can happen) / (total number of outcomes possible) =
(7 ways to draw a green or black marble) / (20 marbles that can be drawn) = 7/20 chance of getting a green or black marble.
Then, because there is a 7/20 chance of getting what we want, and there are 100 draws, we can say that an we should get green or black
7/20 * 100 = 35 times, or D

The rectangle shown has a perimeter of 98 cm and the given area. Its length is 7 more than 5 times its width. Write and solve a system of equations to find the dimensions of the rectangle.
Answer:
35 is its width and 63 is its length.
Step-by-step explanation:
7 x 5 = 35 and 98 - 35 equals 63 which is the length.

find the value of x in the isosceles triangle shown below.
V80
V80
Answer:
Option A. x = 8
Step-by-step explanation:
Please see attached photo.
From the attached photo,
we shall determine the value of y. This can be obtained by using pythagoras theory as illustrated below:
(√80)² = 8² + y²
80 = 64 + y²
Collect like terms
80 – 64 = y²
16 = y²
Take the square root of both side
y = √16
y = 4
Finally, we shall determine the value of x. This can be obtained as follow:
From the attached photo,
x = 2y
but:
y = 4
Therefore,
x = 2y
x = 2 × 4
x = 8

Math help/ battle !!
Answer:
The missing angle is 40 degrees
Step-by-step explanation:
Tan = opposite / adjacent
Tan ? = 24 / 29
24 / 29 = 0.8275
Tan-1 of 0.8275 is 39.610
Round to the nearest degree
39.610 = 40
Answer:
Step-by-step explanation:
Here you have a right triangle with the side lengths 24 and 29 and are asked to find the measure of the smallest angle.
In cases like this you should ask yourself which trig function includes the lengths of the legs (that is, the lengths of the side opposite the angle and the side adjacent to the angle). That would be the tangent function, and so:
tan (?) = (opposite side) / (adjacent side)
Here, tan x = 24/29 = 0.691. Note: I used my TI-83Plus calculator to determine that the measure of angle x in radians is 0.691.
The unknown angle is 0.691 radians, or (multiplying that by the conversion factor (180/pi) ) 39.6 degrees. To the nearest degree, that'd be 40 degrees.
