The product of 15 and a number X is -75. Write the equation, and solution for X.
Answer: [tex]x = -5[/tex]
Step-by-step explanation:
If a product of 15 and an unknown number equals -75 the equation should look like this:
[tex]15x = -75[/tex]
Now to solve for x:
1. [tex]\frac{15x}{15} = \frac{-75}{15}[/tex]
2. [tex]x = -5[/tex]
The solution for x is -5.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation. Equal treatment should be given to each party.
Given:
The product of 15 and a number X is -75.
So, the expression is
15x = -75
Now, divide 15 on both side
15x/15= -75/15
x= -5
Hence, the value of x is -5.

what would be the measure of angle A?
A. 70 degrees
B. 79 degrees
C. 55 degrees
D. 44 degrees
Answer:
D because that is the smallest angle on there baby doll
Step-by-step explanation:
have a nice day sugar bear
Answer:
D
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
4x + 8x - 9 + 57 = 180, that is
12x + 48 = 180 ( subtract 48 from both sides )
12x = 132 ( divide both sides by 12 )
x = 11
Thus
∠ A = 4x = 4 × 11 = 44° → D

Y=2/3x+2-2x+3y=6
Answer:
answer for y=2/3x+2: y=2/3x+2
answer for -2x+3y=6: x=3/2y-3
pls give brainliest
Answer:
There are infinitely many solutions.
Step-by-step explanation:
There are infinitely many solutions because if you solve the equations, you will find that both of the equations are actually the same, so there is infinitely many solutions.
Showing that both equations are equal: y=2/3x+2 -2x+3y=6
y=2/3x+2 Multiply by 3 on both sides
3y=2x+6 Rearrange (-2x on both sides)
3y-2x=6 More rearrangement
-2x+3y=6 Now, if you look back at the second equation, you will see that they are both the same.

Your sister can get $30 per day, d, for selling clothes at the market. But she has to pay $60 at first for renting a stand. You can get $20 per day for helping your neighbor rake lawns. After how many days will your sister earn as much as you?
Answer:
6 days
Step-by-step explanation:
pay 60 = -60
Let d = the number of days
30d - 60 = sister
20d = me
Equation:
30d - 60 = 20d Move 30 to the other side
-30d -30d
-60 = 20d - 30d Combine liked terms

Jonathan wants to investigate the effect that friction has on the amount of force needed to pull an object over surfaces with different textures.
For his test, he gathers the following materials:
• A 1-kilogram wooden board
• A1-meter length of string
A spring scale
• 1 sheet each of felt, construction paper, coarse sandpaper, and wax paper
• 1 roll of masking tape
Jonathan ties one end of the string around the board and the other end to the hook of the spring scale. He tapes the felt, construction paper,
sandpaper, and wax paper side by side on a tabletop. Then he slowly pulls the board across each of the four different surfaces, one surface at
a time. He records the amount of force it takes to move the board over each surface. Which surface would require the least force to move the
board?

calculate the estimate of the mean height of the students in cm and explain your answer
Step-by-step explanation:
we find the average height of each height first,
t¹= (120+124)/2
=244/2
=122
t²= (124+128)/2
t²= 252/2
t²= 126
t³= (128+132)/2
t³= 260/2
t³= 130
t⁴= (132+136)/2
t⁴= 268/2
t⁴ =134
t⁵= (136+140)/2
t⁵= 276/2
t⁵= 138
so multiplying each height by its frequency we can find the total height, so we have..
total height= (122*7)+(126*8)+(130*13)+(134*9)+(138*3)
= 854+1008+1690+1206+414
= 5172
mean height = total height/total frequency
= 5172/40

Answer:
2/8 or 1/4
Step-by-step explanation:
this is because 2/8+3/8+1/8= 0.75
0.75=3/4
1-3/4=1/4
The amount of pizza left Ethan had his two friends will be 1/4.
