1. What is the solution to the system of equations below?
Y = 3x - 2
6x - 2y = 4
Answer:
InfinitE number of solutions
Step-by-step explanation:
y=3x-2
6x-2y=4
sub value of y in first equation (3x-2) into 2nd equation
6x-2(3x-2)=4
6x-6x+4=4
0+4=4
4=4
since the equation equals on both sides, the answer is infinite number of solutions.
Estimate the solution to the following system of equations by graphing.

There are 1400 students in a school. 49.5% of them are male. How many are female?
Answer: 693 students are female
Step-by-step explanation: Calculating fourty-nine point five of one thousand, four hundred. How to calculate 49.5% of 1400? Simply divide the percent by 100 and multiply by the number. For example, 49.5 /100 x 1400 = 693 or 0.495 x 1400 = 693.
Answer:
707 females
Step-by-step explanation:
1400 x 0.495 = 693
Then,
1400 - 693 = 707
707 are girls.

The table shows some of the years in which the Super Bowl was won by the most points. Find the mean median, mode of the data
mean:
median:
mode:
ps: I’ll mark brainlieat
Answer:
mean - 23.6
median - 23
mode - none
Explanation:
the mean of the data is the sum of all the data divided by the number of data sets. here, it is (25 + 21 + 22 + 23 + 27) ÷ 5 = 118 ÷ 5 = 23.6.
the median of the data is the data set that falls exactly in the middle of all the others when arranged in numerical order. here, it would be:
21, 22, 23, 25, 27
the mode of the data is the data set that occurs the most often. however, none of the data values are repeated in this case, so there is no mode.

A store is having a sale in which all items are 20% off. If p is the original price of an item, then the equation p - 0.2p = 0.8p can be used to find the sale price
find the sale price
help
Answer:
Answer Expert Verified
We are given that there is a 20% sale in the store. Moreover, the sale price of an item is p - 0.2p, where p is the price of the item. So, we get that, p - 0.2p is equivalent to 0.8p

find a20
Answer:
a20 = -108
Step-by-step explanation:
53 - 62 = -9
44 - 53 = -9
35 - 44 = -9
Then the intervall is -9
The first number is 63
63 + (19*-9) = 63 - 171 = -108

Q:6 What is the measure of angle MNQ?
Answer:
107 degrees
Step-by-step explanation:
The angles MNQ and RNP are equal to each other so you set them equal to each other, and solve for x. Than plug that value into either of the equations.
5x-18=4x+7
x=25
5(25)-18= 107
Jane bought 5 hot dogs at h dollars each 3 soft drink at s dollars each what is the total cost in dollars of the hot dogs and the software drinks
Answer:
Total cost = $5h + $3s

Answer:
A = 148
B = 180
C = 32
Step-by-step explanation:
All angles in a triangle must equal 180
to find m you had the two angles you already have 90 and 58 and put those in place of A
Subtract this from 180 to get the remaining degrees
90+58 = 148
180 - 148 = 32
You roll a number cube once.
what is the theoretical probability that you roll a 3 or 4?
Answer:
3 = 1/6 chance 4 = 1/6 chance
Step-by-step explanation:
BECAUSE there are 6 numbers on a number cube and there is no ganruntee that it will land on 4 or 3 so its a 1/6 chance that it will land on them.
Answer:
1/6
Step-by-step explanation:
A dice (Number cube in this case) has six sides, in only which one side is three and one side is 4.

Drew has 4 pieces rope 1 meter long each. He cuts each rope into fifths. How long will each of the fifths be in centimeters?
Answer:
20 CM
Step-by-step explanation:
100 cm = 1 meter
the one meter roope = 100cm
Dvide 100cm by 1/5 to determine the length of each cm
100 cm x 5 = 20
100 cm x 5
A map uses a scale of 3/4 in = 80 miles. If two buildings are 60 miles apart in real life, how far apart would they be drawn on the map?
Given:
The scale of a map is [tex]\dfrac{3}{4}\ in=80\ miles[/tex].
The distance between two buildings is 60 miles.
To find:
The distance between the given building on the map.
Solution:
We have,
[tex]\dfrac{3}{4}\ in=80\ miles[/tex]
It means, 80 miles in real life = [tex]\dfrac{3}{4}\ in[/tex] on the map.
1 mile in real life = [tex]\dfrac{3}{4\times 80}\ in[/tex] on the map.
60 mile in real life = [tex]\dfrac{3\times 60}{4\times 80}\ in[/tex] on the map.
= [tex]\dfrac{180}{320}\ in[/tex] on the map.
= [tex]\dfrac{9}{16}\ in[/tex] on the map.
Therefore, the buildings are [tex]\dfrac{9}{16}\ in[/tex] apart on the map.
Point B has coordinates (1,2). The x-coordinate of point A is -8. The distance between point A and point B is 15 units. What are the possible coordinates of point A?
Answer:
The possible coordinates of point A are [tex]A_{1} (x,y) = (-8, 14)[/tex] and [tex]A_{2} (x,y) = (-8, -10)[/tex], respectively.
Step-by-step explanation:
From Analytical Geometry, we have the Equation of the Distance of a Line Segment between two points:
[tex]l_{AB} = \sqrt{(x_{B}-x_{A})^{2} + (y_{B}-y_{A})^{2}}[/tex] (1)
Where:
[tex]l_{AB}[/tex] - Length of the line segment AB.
[tex]x_{A}, x_{B}[/tex] - x-coordinates of points A and B.
[tex]y_{A}, y_{B}[/tex] - y-coordinates of points A and B.
If we know that [tex]l_{AB} = 15[/tex], [tex]x_{A} = -8[/tex], [tex]x_{B} = 1[/tex] and [tex]y_{B} = 2[/tex], then the possible coordinates of point A is:
[tex]\sqrt{(1+8)^{2}+(2-y_{A})^{2}} = 15[/tex]
[tex]81 + (2-y_{A})^{2} = 225[/tex]
[tex](2-y_{A})^{2} = 144[/tex]
[tex]2-y_{A} = \pm 12[/tex]
There are two possible solutions:
1) [tex]2-y_{A} = -12[/tex]
[tex]y_{A} = 14[/tex]
2) [tex]2 - y_{A} = 12[/tex]
[tex]y_{A} = -10[/tex]
The possible coordinates of point A are [tex]A_{1} (x,y) = (-8, 14)[/tex] and [tex]A_{2} (x,y) = (-8, -10)[/tex], respectively.

Solving systems of equations using substitution y=4x+2 7x-4y=-8
Step-by-step explanation:
7x - 4(4x +2) = -8
7x - 16x -8 = -8
-9x = 0
x = 0
y = 2
Answer:
(0,2)
Step-by-step explanation:
7x - 4(4x + 2) = -8
7x - 16x - 8 = -8
-9x = -8 = -8
-9x = 0
x = 0
y = 4(0) + 2
y = 2
