Find the midpoint of the segment with the given endpoints
(-9,-9) and (7,5)
Answer:
(-1, -2)Step-by-step explanation:
Given points
(-9,-9) and (7,5)Midpoint is
((-9 + 7)/2, (- 9 + 5)/2) =(-2/2, -4/2) =(-1, -2)Natalie and her sister opened savings accounts at the same time. Natalie deposited $100 and will deposit $10 each month. Her sister deposited $25 and will deposit $25 each month. When will Natalie have less money in her account than her sister?
Answer:
5
Step-by-step explanation:
Natalie
100 + 10x
Her sister
25 + 25x
Where
x = number of months
Equate Natalie and her sisters equation
100 + 10x < 25 + 25x
100 - 25 < 25x - 10x
75 < 15x
Divide both sides by 15
x < 75 / 15
x < 5
3)A recipe calls for 1 3/4 cups of rice.
a) How many rice needed to make half the rice???
b) How much rice is needed to make two and one half times the recipe???
Answer:
A) 7/8 cups B) 4 3/8 cups
Step-by-step explanation:
1 3/4 = 7/4
7/4 cut in half is 7/8
7/4 doubled is 7/2
7/2 = 28/8
28/8 + 7/8 = 35/8
35/8 = 4 3/8
Answer:
a) 7/8 cupsb) 4 3/8 cupsStep-by-step explanation:
Given
Full recipe = 1 3/4 cups of rice
1 recipe ⇒ 7/4 cupsa) half of the recipe
1/2 recipe ⇒ 1/2*7/4 = 7/8 cups of riceb) 2 and one half time the recipe
2 1/2 recipe = 5/2 ⇒ 5/2 * 7/4 = 35/8 = 4 3/8 cups of riceDetermine the equation of the line shown in graph:

For spirit week at a local high school, students were encouraged to wear their school colors of green and white. 1,200 students wore their school colors while 300 students did not wear green and white. What percent of the school population wore their school colors?
Answer:
80%
Step-by-step explanation:
We are told that 1,200 students wore their school colors of green and white.
Also, we are told that 300 students did not wear school colours green and white.
Thus, total number of students = 1200 + 300 = 1500
Thus;
percent of the school population who wore their school colors is; (1200/1500) × 100% = 80%

Answer:
y = [tex]\frac{5}{4} x - 7[/tex]
Step-by-step explanation:
Step 1: Add -5x to both sides.
5x − 4y + −5x = 28 + −5x
−4y = −5x + 28
Step 2: Divide both sides by -4.

Step-by-step explanation:
Dominic is going to drive from his house to City A without stopping. Dominic's house is 300 miles from City A and he plans to drive at a speed of 50 miles per hour. Write an equation for D, in terms of t,t, representing Dominic's distance from City A t hours after leaving his house.
Answer:
D= −50t + 300
Step-by-step explanation:
Since Dominic lives 300 miles from City A, when he starts his trip (at time
t=0), his distance from City A must be 300 miles, meaning D=300 when
t=0, which is the y−intercept.
(0,300) is a point on the graph
Since Dominic will drive 50 miles per hour, the Dominic's distance from City A decrease 50 miles for each hour of driving, making the slope of D equal to
−50.
Slope=−50
equation of the line: D= −50t + 300
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The equation for D, in terms of t, represents Dominic's distance from City A t hours after leaving his house.
D = 300 - 50t
Where t= number of hours
What is an equation?
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x = 4 is an equation.
We have,
Distance between Dominic's house and City A = 300 miles
Speed = 50 miles per hour.
The equation for D, in terms of t, represents Dominic's distance from City A t hours after leaving his house.
D = 300 - 50t
Where t= number of hours
Now,
We can see that,
At t = 1, D = 300 - 50 = 250 miles.
At t = 2, D = 300 - 100 = 200 miles.
Thus,
The equation for D, in terms of t, represents Dominic's distance from City A t hours after leaving his house.
D = 300 - 50t
Where t= number of hours

6x-2x=24 HELP PLSSSSSS
Answer:
x=6
Step-by-step explanation:
Basically since 6x and 2x have like terms you subtract the 2x from 6x.
6x-2x=4x
Then you divide 4 from 24.
4x=24
4x/4 = 24/4
x=6
Answer:
6x - 2x = 24
4x = 24
4x ÷ 4 = 24÷4
x = 6
Step-by-step explanation:
First of all subtract 2x from 6x which will give you 4x = 24
since you're finding x or want to make x the subject you are to divide both sides by 4, so
4x ÷ 4 will give you x, since both 4's will cancel out giving you x =, then you divide 24 by 4 also. 24 ÷ 4 will give you 6, so x = 6.
