2 answers:

7 0

first you take 63 and 81 add them together you get 144 then divide by 2 because you have two numbers then you get 72.which means he got a 66% on his last test here is the work:

63+81+66=210

210 divided by 3=

70%

hope this helps

Identify the type of triangle that can be drawn using the measures of sides 13.5 cm, 5 cm, and 9.5 cm.

KIM [24]

Answer: Scalene triangle

Step-by-step explanation:

A Scalene triangle has all of its three lengths to be different. The traingle above can not be an equilateral triangle too because all the sides aren't equal.

Also, it's not an isosceles triangle since two of its sides are not thesame. It's not a right angle triangle as the square of the hypothenuse isn't equal to the addition of the square of the other two sides.

Solve the following system of equations 3x+4y=16 and -4x-3y = -19

BigorU [14]

3x + 4y = 16
-4x - 3y = -19

4( 3x + 4y = 16)
3( -4x - 3y = -19)
Distribute
12x + 16y = 64
-12x - 9y = -57
Now subtract both equations
7y = 7
/7 on both sides
y = 1

Substitute y = 1 in one of the equations.
3x + 4y = 16
3x + 4(1) = 16
-4 on both sides
3x = 12
/3 on both sides
x = 4

Answer:
x = 4
y = 1

Write an expression to represent:One more than the quotient of a number X and 4

astra-53 [7]

Answer:

X/4 +1

Step-by-step explanation:

The word "quotient" tells us that we'll be dividing X and 4.

This can be modeled as X/4

To this quantity, we will be adding 1.

We now get X/4 +1

5x + 2y = 34<br> x= - 4y - 4

tiny-mole [99]

Answer:

y = -3

Step-by-step explanation:

So, first you need to plug in -4y-4 for x. So, 5(-4y-4) + 2y=34. Now, use the distributive property and now it will become -20y -20 + 2y = 34. Add like terms which would be -20y + 2y = -18y. Now the equation is -18y - 20 = 34. Now use inverse operations and add 20 to both sides. Then the equation will be -18y = 54. When you divide -18 on both sides, you get y=-3.

Hope this helps :)
