Please help my 5th Grade brother for this question.
Answer:
1 1/5
Step-by-step explanation:
You need to multiple 3 times 2 and you get 6 so 6/5 (as improper fraction) As a mixed number its 1 1/5
Chose the equation of the line in slope-intercept form.
Answer:
Third answer choice
Step-by-step explanation:
Y intercept of the graph is -3 so you can eliminate the first two choices.
Then you see the slop is going up so its positive so you can eliminate the negative slope answer choice.
You are then left with the third answer choice and that is your answer.

Need help thank you.
Answer:
x = 20
Step-by-step explanation:
The three angles make up a straight line.
A straight line has 180 degrees.
x + 3x + 100 = x80 Combine
4x + 100 = 180 Subtract 100 from both sides
4x = 180 - 100
4x = 80 Divide by 4
x = 80/4
x = 20
What is the slope between these two points? (2,5) (8, 12)
Answer:
7/6
Step-by-step explanation:
y2-y1/x2-x1(slope formula)
plug in numbers
12-5=7
8-2=6
hence 7/6

A gym membership costs $25 to join, plus a $12 monthly fee. If Adam has spent $133 on his gym membership this year, for how many months has he been a member?
Answer:
133= 12x +25 (subtract 25 from both sides to isolate the x-term)
108= 12x (divide by 12 on both sides to get x alone)
x= 9 months

Answer:
The answer is D. or 16 3/4
Step-by-step explanation:
Choose the description that matches the inequality p > -3.
A line traveling to the left with an closed dot on p = -3.
A line traveling to the right with an closed dot on p = -3.
A line traveling to the left with an open dot on p = -3.
A line traveling to the right with an open dot on p = -3.
Answer:
D
Step-by-step explanation:
Anything saying left is incorrect. Numbers going to the left are smaller than - 3.
The dot is not filled in. To have a closed dot you would need ≥
The answer is D

Show your work and use mathematical vocabulary
to explain your reasoning.

8
Answer:
13.4 inches
Step-by-step explanation:
Firstly you should calculate the diagonal of lower square using pythahoras theorem
I.e diagonal = (89)^1/2
Now calculate distance by simple arithmetic
X=Xx + Xy
= (89)^1/2 + 4
= 13.4
Answer:
√105 inches
Step-by-step explanation:
The diagonal of the bottom is the hypotenuse of a right triangle with legs measuring 5 and 8.
a² + b² = c²
5² + 8² = c²
c² = 89
c = √89
The path of the spider is the hypotenuse of a right triangle whose legs measure √89 and 4.
a² + b² = c²
(√89)² + 4² = c²
89 + 16 = c²
c² = 105
c = √105
Diego works at a warehouse that ships two types of packages, a red package weighing 4 pounds and a blue package weighing 6 pounds. Diego shipped a total of 40 packages weighing 180 pounds.

20 packages
30 packages
Answer:
10 packages
Step-by-step explanation:
red = 4p
blue = 6p
total 40 packages and 180p
180 divided by 40 is 4.5
how many blue packages?
5x6=30p 35x4=140 no
10x6=60p 30x4=120 yes

Find the value of x and y
Answer:
x = 15, y = 38
Step-by-step explanation:
2sides of the triangle are congruent, thus triangle is isosceles.
The 2 base angles are therefore congruent and since right isosceles triangle
Then each base angle = 45°, then
3x = 45 ( divide both sides by 3 )
x = 15
and
y + 7 = 45 ( subtract 7 from both sides )
y = 38
