c - 12 = -14
and
7 + x = -1
plz help thank you
Answer: x= -2, c= -8
Step-by-step explanation: To solve the first equation, move the 12 over to the right side. To do this, do the oposite operation. So add 12 on both sides. The 12 on the left side cancels out, and you are left with x= -14+12. X=-2. Do the same thing for the next equation. Subtract 7 from the left side and the right side. C= -1-7. C= -8

how many bricks each 22 cm long and 15 CM broad will be required to pave a court 30 metre long and 22 wide
Answer:
BBBBBBBBBBBBBBBBBBBB
Step-by-step explanation:
CAUSE I SAID SO
Answer:
20,000 bricks
Step-by-step explanation:
length of brick(L)=22cm
breadth of brick(B)=15cm
now,
area of brick(A)=L×B
=22×15s.q.cm
=0.033s.q.m
again,
length of court(l)=30m
breadth of court(b)=22m
now,
area of court(a)=l×b
=30×22s.q.m
=660s.q.m
lastly,
no.of required brick=area of court/area of
brick
=600 s.q.m/0.033s.q.m
=20,000bricks
In the rhombus ABCD, ĐDAE = 30°. Which is ĐABC?
309
D
C
A.
30°
OB.
60°
c.
120°
OD.
150°
Answer:
C. 120 deg
Step-by-step explanation:
All sides of a rhombus are congruent.
That means that triangle ADC is an isosceles triangle with AD = CD, so angles DAE and DCE are congruent.
m<DAE + m<DCE + m<ADC = 180
30 + 30 + m<ADC = 180
m<ADC = 120
Opposite angles of a rhombus are congruent, so
m<ABC = m<ADC = 120

9. Ian and his friends are renting a cabin that
charges an initial fee plus a rate per night. The
relationship between the cost and the number of
nights is shown in the graph.
Answer:
taken from another post
Step-by-step explanation:
Answer:
Cost per night: 75
Equation:
Step-by-step explanation:
An equation to represent the situation can be written in the slope-intercept form, , where,
m = slope of the graph, which is the rate per night.
b = y-intercept, which is the initial fee. It is the point where the line intercepts the y-axis.
Let's find m, using two points on the line, (2, 200) and (4, 350)
✅The cost per night = 75
y-intercept, b, = 50. The line intercepts the y-axis at y = 50, when x = 0.
Substitute m = 75, and b = 50 into .
✅The equation would be:
What is the answer...?
Answer:The answer is c
Step-by-step explanation:
Multiply both side is the equation by -1.
Sum the equations vertically to eliminate at least one variable
Divide both sides of the equation by 3
Substitute the given value of y into the equation 2x+3y=8
and then solve for x

Can someone help me with those questions? (Try your best plzz)
Answer:
Step-by-step explanation:
1. 34 animals because of 34 heads.
94 legs: 4 per cow, 2 per chicken
x= # of cows
y= # of chickens
so x+y=34
4x+2y=94
Multiply the first equation by -2 is -2x-2y=-68 and add it to the first equation.
which is 2x=26. so x=13. Since x+y=34, 13+y=34.
Therefore, y=21
13 cows and 21 chickens.
2. lets say
pizza=y
soda=x
6x+x=14 combine like terms
7x=14 divide both sides by 7
x=2
So a soda is $2.
6*2=12. So the pizza is $12.
12+2=14. So it's correct.
3.
# of DVDS=x
# of Bluray= y
11x+17y=95
x+y=7
dvds-4
blu-ray-3 (I just did trial and error, but it's correct)
4.
# of 2-points= x
# of 3-points= y
2x+3y=18
2(6)+3(2)=18
so 6 two-point shots and 2 three-point shots.
5.
12 coins are quarters and 14 are dollar coins.
let q stand for the number of quarters
and 26 coins in total
26-q= dollar coins
x=dollar coins too
so its 1x+.25(26-x)=17
1x+6.5-0.25x=17
.75x+6.5=17
.75x=10.5
x=14
17-14=3
3*4= 12 since 4 quarters in a dollar.

Bridget is on her middle school’s basketball team. In it’s last game, her team made 31 of it’s shots. Some of those were free throws, worth 1 point each, & some of those were regular field goals, worth 2 points each. The team didn’t make any 3 pointers and finished the game with 49 points. This system of equations can be used to represent the situation
X + y = 31
X + 2y = 49
Which statement is correct
(statements are at the top aka the picture I provided)
How many points did Bridget’s team score from the field goals?
Answer:
Step-by-step explanation:
Let the number of free throws = x
And the number of regular field goals = y
Total shots made by the team = 31
Equation for the shots will be,
x + y = 31 ------(1)
If the team gets 1 point for free throws and 2 points for a regular field goal,
x + 2y = 49 --------(2)
[total points gained by the team = 49]
1). Option (2) is the correct option.
2). Subtracting equation (1) from equation (2),
(x + 2y) - (x + y) = 49 - 31
y = 18
Therefore, number of regular field goals made by the team = 18

What is the slope of a surface having a rise of 5 feet and a run of 0 feet?
Answer: The slope is "undefined."
Step-by-step explanation: In math, division by 0 is undefined-- like you can't do it
For slope, you need to divide rise/run. If the run is 0, so undefined.
In real life, this surface would be like a wall or a door. They don't have a slope if they're constructed properly!
