x+y=15
- 2x+5y=-2
solve the system of equations
please answer i’ll name you brainliest
Answer:
x= 11 and y = 4
Step-by-step explanation:
(solving by elimination)
Multiply the first equation by 2 and multiply the second one by 1.
2(x+y= 15)
1(-2x+5y=-2)
is now
2x+2y=30
-2x+5y-2
add them together to eliminate x
7y=28
then solve for y
7y=28
[tex]\frac{7y}{7}[/tex]=[tex]\frac{28}{7}[/tex]
y=4
---
Now you have y. put that back into the original equation for X
---
x+y=15
y= 4 so
x+4=15
x= 15-4
x=11
x=11, y=4
A map with a scale of 2:in:350 mi shows two cities to be 6 inches apart. How many miles apart are the cities?
Answer:
1050miles.
Step-by-step explanation:
since every 2 inches=350 miles, then 6 inches= 3(350miles)
since 6/2=3.
or you can think of it this way:
there are 3 2-inches in 6 inches, and every 2 inches, it's 350s miles.
350+350+350=1050miles.
What is the measure of Zx?
Angles are not necessarily drawn to scale.
Answer:
This question is straightforward if you find different triangles in the figure itself.
Property of a triangle: All internal angles of a triangle must add up to 180°
Take a look at Triangle DBH.
Method A
Angle BHD = 180°-33°-46° (sum of angles in a triangle)
= 101°
Property of angles on a straight line: All angles on a straight line must add up to 180°
Angle x = 180°-101° (supplementary angles)
= 79°
Method B
Take a look at Triangle DBH.
Property of exterior angle (in this case, angle x): An exterior angle of a triangle is equal to the sum of its two opposite non-adjacent interior angles.
Angle x = 33°+46°
= 79°
A scale drawing for a rectangular parking lot measures 5.3 cm by 7.5 cm.
The scale is 2 cm:7 m. What are the width of the actual parking lot, if the
drawing width is 7.5 cm?
=====================================================
Work Shown:
(2 cm)/(7 m) = (7.5 cm)/(x meters)
2/7 = 7.5/x
2x = 7*7.5
2x = 52.5
x = 52.5/2
x = 26.25
7.5 cm on paper corresponds to 26.25 meters in real life.
side note: 26.25 meters = 86.122 feet approximately

A backyard measures 30 feet by 40 feet. If the owner builds a fence around, about how many feet of fencing will be needed?
Answer:
140 feet
Step-by-step explanation:
You will need to find the perimeter of the backyard to find how many feet of fencing will be needed
the formula for perimeter is: 2l+2w
So 2 times 30 is 60
with 2 times 40 80
60+80 is 140
Thus you will need 140 feet to cover the backyard
Hope this helps!
Answer:
140 ft
Step-by-step explanation:
Perimeter = 2(l+w)
Perimeter = 2(30+40)
Perimeter = 2(70)
Perimeter = 140
2+5+8+….+3n-1=n(3n+1)/2

The graph shows a nonstandard normal distribution curve with
a mean of 59.0 and a standard deviation of 6.7.
Find the area of the shaded region.
.7761
.2177
.3650
.7823
Using the normal distribution, it is found that the area of the shaded region is of 0.7823.
In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem:
The mean is of 59, hence [tex]\mu = 59[/tex].The standard deviation is of 7, hence [tex]\sigma = 7[/tex].The shaded region is the region to the left of 64.2, hence it's area is the p-value of Z when X = 64.2.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{64.2 - 59}{6.7}[/tex]
[tex]Z = 0.7761[/tex]
[tex]Z = 0.7761[/tex] has a p-value of 0.7823.
The area of the shaded region is of 0.7823.

Marcus monthly salary is $1,500 plus 10% of sales. How much could Marcus earn per month with salary and 10% sales? Please explain your answer.........
Answer:
1500 + x(0.1)=salary
Step-by-step explanation:
Without a sales value, what I'm assuming you want is the equation to find his salary
Using a y=mx+b equation, we find that the b=1500, while m (the slope) is equal to 10%/100 and x is the dollar ammount in sales marcus has made, with y being this months paycheck
so we end up with an equation of 1500 +0.1x=y

Robert and Tony love to read. Robert reads 30 pages the first day and 20 pages each day after that. Tony reads 40 pages the first day and 15 pages each day after that. Will the boys ever read the same amount of pages? If so, how many days will it take them to read the same number of pages? A. Yes. They will read the same amount of pages in 3 days. B. Yes. They will read the same amount of pages in 5 days. C. Yes. They will read the same amount of pages in 6 days. D. No. They will never read the same amount of pages.
Answer:
Yes they will read the same amount of pages in 3 days
Step-by-step explanation:
Because when you do the math they add up to the same amount of pages.
The correct statement is;
''Yes. They will read the same amount of pages in 2 days.''
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Robert reads 30 pages the first day and 20 pages each day after that.
And, Tony reads 40 pages the first day and 15 pages each day after that.
Now,
Let the number of days for same pages read = x
So, We can formulate;
For Robert;
Number of pages = 30 + 20x
For Tony;
Number of pages = 40 + 15x
For equal days, we get;
⇒ 30 + 20x = 40 + 15x
Solve for x as;
⇒ 20x - 15x = 40 - 30
⇒ 5x = 10
⇒ x = 2
Thus, The correct statement is;
''Yes. They will read the same amount of pages in 2 days.''

I need helppp pleaseee
Answer:
One solution
Step-by-step explanation:
Start by simplifying the equation.
Distribute 3 to 4 and 2 to get 12x + 6Combine 8x and -2x to get 6xThen you have 12x + 6 = 6x + 24,
Continue to solve
Subtract 6 from the left and right to get 12x = 6x + 18Subtract 6x from both sides to get 6x = 18Divide both sides by 6 to get x = 18Because x is equal to one digit and not x = x or 3 = 5, you have one solution
(Infinite) or (none)
