Answer:

x = 3 and y = 5

Step-by-step explanation:

Given equations are :

y=5x−10 ..(1)

y=−3x+14 ...(2)

Subtract equation (2) from (1).

y-y = 5x−10-(−3x+14)

0 = 5x-10+3x-14

0= 8x-24

8x = 24

x = 3

Put the value of x in equation (1).

y=5(3)−10

= 15-10

y = 5

So, the values of x and y are 3 and 5 respectively.

Answer: $15.75

Step-by-step explanation:

From the question, we are informed that a storekeeper increased the price of hats by 5% and that the hat was originally priced at $15.00.

The new cost of the hat will be:

= $15.00 + (5% × $15.00)

= $15.00 + (5/100 × $15.00)

= $15.00 + (0.05 × $15.00)

= $15.00 + $0.75

= $15.75

The new cost of the hat is $15.75

Answer:

145) A

146) C

147) B

148) D

Step-by-step explanation:

_____________________145_____________________

Starting with number 145 it mentions that XY = 24 and XY:YZ = 1:2.

XY:YZ means ratio of XY over YZ so for each 1 XY there is 2 YZ.

Moving on and taking note that XY=24 so this means that,

[tex]\frac{XY}{YZ} =\frac{24}{YZ}= \frac{1}{2}[/tex]

Solving the above expression by cross multiplying 24x2 will give you YZ = 48. The same method applies to #146 and #148 the next questions.

_____________________146_____________________

YZ = 9 and XY:YZ=2:3

[tex]\frac{XY}{YZ} =\frac{XY}{9} =\frac{2}{3}[/tex]

XY= (2x9)/3 = 6

XY = 6

_____________________147_____________________

Given:

XZ = 2ft

YZ = 18in

In this question, you will have to refer to the proportion line given above the questions. It mentions that XZ = 2ft (which is the whole line) and YZ = 18in (which is from Y to Z). Take note that the units are not the same.

They're looking for XY which is the only unknown length in the given proportion line. To get XY you'll have to subtract XZ - YZ, but the units are not the same so you'll have to convert feet to inches since the answer options are given in inches.

Convert 2ft to inches:

To convert from feet to inches you'll have to multiply by 12 so 2x12 = 24.

Therefore, XZ = 24in

Now we subtract:

XZ - YZ = XY

24 - 18 = 6in

_____________________148_____________________

YZ = 1ft

XY: YZ = 1:4

YZ is given in feet and the answers are provided in inches so we'll have to convert.

1 x 12 = 12in

YZ = 12in

[tex]\frac{XY}{YZ} =\frac{XY}{12} =\frac{1}{4}[/tex]

XY = (1x12)/4 = 3in

Answer:

-12degrees Celsius

Step-by-step explanation:

-3+5=2 1:00pm

2-2=0 6:00pm

(10-6=4)

4(3)=12, 0-12=-12 10:00pm

i hope this helps!

Answer:

-12° C

Step-by-step explanation:

Temperature at 8 a.m.: -3° C

From 8 a.m. to 1 p.m. the temperature went up 5° C.

-3° C + 5° C = 2° C

Temperature at 1 p.m.: 2° C

By 6 p.m. the temperature was 2° C colder than at 1 p.m.

2° C - 2° C = 0° C

Temperature at 1 p.m.: 0° C

The temperature decreased 3° C per hour from 6 p.m. to 10 p.m.

From 6 p.m. to 10 p.m., it's 4 hours. The temperature decreased 3° C per hour for 4 hours. 4 * 3° C = 12° C. The temperature went down 12° C altogether from 6 p.m. to 10 p.m.

0° C - 12° C = -12° C

Temperature at 10 p.m.: -12° C

Answer: -12° C

No.

Answer:

y-intercept= (0, 0.4)

x-intercept = (0.3, 0)

Step-by-step explanation:

The intercept is where the line crosses the axis, and a coordinate is written out as, (x,y).

With this knowledge in mind, for the y-intercept, the x coordinate would be 0, and the y coordinate would be 0.4, which is where it crosses the y axis. This would make the y-intercept (0, 0.4).

For the x-intercept, the y coordinate would be 0, and the x coordinate would be where the line crosses the axis, making it 0.3. With these numbers and coordinates in mind, the coordinate for where the line intercept the x axis is (0.3, 0).

Answer:

x ≈ 2.55

Step-by-step explanation:

Since the triangles are congruent then DE ≡ AB , that is

DE = AB

76x - 7 = x + 184 ( subtract x from both sides )

75x - 7 = 184 ( add 7 to both sides )

75x = 191 ( divide both sides by 75 )

x ≈ 2.55 ( to the nearest hundredth )

Answer:

heyy there sorry i wish i could help i think its the first one!!!

Step-by-step explanation:

Answer:

One solution

Step-by-step explanation:

In a one- variable equation has infinitely many solutions when solving results in a true statement, such as 2=2

In a one- variable equation has one solution when solving results in one value for the variable, such as x = 5

In a one - variable equation has no solution when solving results in an untrue statement, such as 2=3

So, in this case the result x = -2 belongs to the 2nd sentence where it says one solution.

Hope this helps :)

Answer: 20

Step-by-step explanation:

first you make it into a equation

then you have to make both sides equal the same thing by doing that you figure what t is and t will be your answer

100=2(t)+3(t)

100=2(20)+3(20)

100=40+60

100=100

t=20

It will take 20 seconds for the students to bump into one another.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Student A, has a speed of 2 meters each second;

Student B, has a speed of 3 meters each second.

Let's suppose they start to walk to each other when t=0.

first we will make it into a equation then we have to make both sides equal the same thing by doing that you figure what t is and t will be your answer.

100=2(t)+3(t)

100=2(20)+3(20)

100=40+60

100=100

t=20

Therefore, it will take 20 seconds for the students to bump into one another.
