Step-by-step explanation:
5x-12=13
5x -12 =13
+12=+12
5x= 25
5 =. 5
x=5
5x - 12 = 13
5x = 13 + 12
5x = 25
25 divided by 5 is 5
Answer: x = 5
Westminster Street and Lake Avenue intersect. If Westminster Street is 7 meters wide and Lake Avenue is 5 meters wide, what is the distance between two opposite corners of the intersection? If necessary, round to the nearest tenth.
Answer:
the distance between two opposite corners of the intersection is 8.60 meters
Step-by-step explanation:
The computation of the distance between two opposite corners of the intersection is given below:
Here we applied the Pythagoras theorem
[tex]= \sqrt{7^2 + 5^2} \\\\= \sqrt{49 + 25} \\\\= \sqrt{74}[/tex]
= 8.60 meters
hence, the distance between two opposite corners of the intersection is 8.60 meters
How come two negatives make a positive, but three negatives makes a negative? Does this have to do with there being an odd/even amounts of negatives and cancelling each other out?
Okay well work step by step. If there is three negatives, you first want to multiply the first two negatives. Your number will come out positive but you are still left with one more negative. so you will multiply the positive number with the negative number which comes out with a negative number.
Convert: 0.1477km =
m*
Answer:
147.7 meters
Step-by-step explanation:
kilo means 'thousands' so you have to move the demical 3 places to the left to make .1477 a thousand times larger
also, you could set up a proportion like the following based on 1km = 1000m
1000 m = x
1 km .1477
x = .1477 x 1000
x = 147.7
I'm stuck on this question and this is my third Time posting about it pls help me look at pic
Answer:
m = 11, and the correct equation is m + 7.28 = 18.28
Step-by-step explanation:
First, we need to solve:
0.2*m = 2.20
To do it, we need to divide by 0.2 in both sides:
0.2*m/0.2 = 2.20/0.2
m*(0.2/0.2) = 11
m = 11
Ok, we know the value of m.
Now we need to input the value of m in each one of these 4 equations and see which one is the correct one.
The correct equation is;
m + 7.28 = 18.28
When we replace m by 11, we get:
11 + 7.28 = 18.28
So the equation is correct.
A train leaves at 1314 and arrives at 1508. It travelled at an average speed of 105 km/h.
How far did it travel? Give your answer in km to 1DP
Answer: The train traveled 199.5 km
Step-by-step explanation:
We know the relationship:
Distance = Time*Speed
We know that the speed of the train was 105km/h
And we know that it leaves at 13:14, and arrives at 15:08.
Then the total amount of time that the train was traveling is:
T = (15 hours and 8 mins) - (13 hours and 14 mins)
= (15 - 13) hours and (8 - 14) mins
= 2 hours and (-6) mins.
We know that one hour has 60 minutes, then this is equal to:
T = 1 hour and 54 minutes.
But because the speed is kilometers per hour, we need to rewrite the 54 minutes in hours.
This can be done as follows:
1 hour = 60 minutes.
Then: 54 minutes = (54/60) hours = 0.9 hours.
Then:
1 hour and 54 minutes = 1.9 hours.
Now we know the speed and the time, then the distance can be calculated as:
Distance = speed*time = 105km/h*(1.9 h) = 199.5 km
The train traveled 199.5 km
Answer:
The train traveled 199.5 km
Step-by-step explanation:
We know the relationship:
Distance = Time*Speed
We know that the speed of the train was 105km/h
And we know that it leaves at 13:14, and arrives at 15:08.
Then the total amount of time that the train was traveling is:
T = (15 hours and 8 mins) - (13 hours and 14 mins)
= (15 - 13) hours and (8 - 14) mins
= 2 hours and (-6) mins.
We know that one hour has 60 minutes, then this is equal to:
T = 1 hour and 54 minutes.
But because the speed is kilometers per hour, we need to rewrite the 54 minutes in hours.
This can be done as follows:
1 hour = 60 minutes.
Then: 54 minutes = (54/60) hours = 0.9 hours.
Then:
1 hour and 54 minutes = 1.9 hours.
Now we know the speed and the time, then the distance can be calculated as:
Distance = speed*time = 105km/h*(1.9 h) = 199.5 km
The train traveled 199.5 km

Angle A and Angle B are complementary. If angle A is 48°, what is the measure of angle B?
Answer:
B = 42°
Step-by-step explanation:
hope it help
plz fo"ow me
The measure of the angle B when angle A and angle b is complementary angle should be 42 degrees.
Calculation of the measure of angle B:Since
Angle A and Angle B are complementary. And, angle A is 48°.
We know that
The sum of complementary angles is 90 degrees
So it can be like
A + B = 90
48 + B = 90
B = 90 - 48
= 42 degrees
hence, The measure of the angle B when angle A and angle b is complementary angle should be 42 degrees.

Answer:
X=0
Step-by-step explanation:
Use PEMDAS to get rid of some things. Do 3 x 2 = 6. Then distribute the like terms to one side seperating 2x and "0": +1 ---> 0-1 = -1. Now divide... 2x/2 = x (cancels out) and 0/2 = 0. Therefore X=0. But I'm not a computer so double check your answer.

Mark wants to make an enclosure for his cows.
He has 44 metres of fencing.
He wants the width to be 8 metres less than the length.
What dimensions should the field have?
?
Answer:
the length and width be 15 meters and 7 meters respectively
Step-by-step explanation:
The computation of the dimension of the field is given below;
Let us assume the fencing be p
Length be x
And, the width be x - 8
So,
P = 44
P = x - 8 + x - 8 + x + x
= 4x - 16
Now
4x - 16 = 44
4x = 44 + 16
4x = 60
x = 15
And, the width be 15 - 8 = 7
So, the length and width be 15 meters and 7 meters respectively

If f(x)=2x−2 and g(x)=x2−8x+19, then f(x)=g(x) for what values of x?
x=−1 and x=−4
x=−3 and x=−7
x=1 and x=4
x=3 and x=7
Answer:
D) x =3 and x =7
Step-by-step explanation:
Step(i):-
Given function f(x) = 2x -2
g(x) = x² - 8x +19
Given that f(x) = g(x)
⇒ 2x -2 = x² - 8x +19
⇒ x² - 8x +19 -2x +2 =0
⇒ x² -10x +21 =0
Step(ii):-
The factors are x² -10x +21 =0
⇒ x² - 7x - 3x +21 =0
⇒ x( x-7) -3( x-7) =0
⇒ (x-3)(x-7) =0
x =3 and x =7

A farmhouse shelters 14 animals. Some are
pigs, and some are chickens. Altogether there
are 44 legs between the animals. Let p
represent the number of pigs and c represent
the number of chickens.
9514 1404 393
Answer:
8 pigs6 chickensStep-by-step explanation:
Maybe you want to know the number of each kind of animal.
__
We can write two equations in the two unknowns.
p + c = 14 . . . . . . number of animals
4p +2c = 44 . . . number of legs
Dividing the second equation by 2, it becomes ...
2p +c = 22
Then subtracting the first equation gives ...
(2p +c) -(p +c) = (22) -(14)
p = 8
8 +c = 14
c = 6
The farmhouse shelters 8 pigs and 6 chickens.

C. 12 ⋅ 1.25
D. 12 ⋅ 0.25
E. 12 + 0.25
Answer:
A, B, C
Step-by-step explanation:
12+0.25*12=12(1+0.25)=12*1.25
Answer:
B. 12 + 0.25 ⋅ 12
C. 12(1 + 0.25)
Step-by-step explanation:
It asks you how far she walks all together, so you need to find that answer first to figure out the rest correctly. Now, the total she walked is 15 miles. B. and C. give you 15, however, the rest give you different answer than the total she actually walked.
