A map uses the scale 3/4 of an inch to represent 3 miles. If the actual
distance between two cities is 25 miles, then what is the length on the
map?
Answer:
6¼ in
Step-by-step explanation:
¾ = 0.75
25 mi ÷ 3 mi = 8.333
8.333 * 0.75 in = 6.25 in = 6¼ in
5x = 40 what does the x going to equal
start by diving 5 from each side so you are lrft with x on the left side, 40/5=8. now our equation is x=8 and that's the answer!
Answer:
[tex]x=8[/tex]
Step-by-step explanation:
Given the following question:
[tex]5x=40[/tex]
When solving one-step equations, you need to remember we are trying to isolate the variable. In this case to isolate the variable we need to divide both sides by 5.
[tex]5x=40[/tex]
[tex]5x\div5=x[/tex]
[tex]40\div5=8[/tex]
[tex]x=8[/tex]
Which means the value of x will be "8."

Given the equation 2x = 4y - 3 write another linear equation that would create a system that has the number of solutions listed
A . 0 Solutions
B . 1 Solution
C . Infinitely many solutions
Answer:
A. [tex]2x-4y=\pi[/tex]
B. [tex]x=1[/tex]
C. [tex]2x-4y=3[/tex]
Step-by-step explanation:
A. [tex]2x-4y=\pi[/tex]. Any number could work as long as the coefficients for x and y stays the same. You are basically imposing that the quantity 2x-4y (if you bring 4y to the LHS) is equal to both -3 AND [tex]\pi[/tex], or any number you like. But yesterday was 3/14 so let's pick a fun number!
B. [tex]x=1[/tex] Or [tex]y=1[/tex]. Or as long as you don't pick the same ratios of x and y you're golden. But x=1 is the easiest that comes to mind
C. [tex]2x-4y=3[/tex]. To get infinitely many solutions you just have to rewrite the equation again. Maybe move things around if you prefer, or multiply everything by a number you lile.

Place the following temperatures in order from coldest to hottest: -8°C, 10°C, -5°F, 40°F
a.
-5°F, -8°C, 40°F, 10°C
b.

ANSWER IS A
Answer:
a. -5°F, -8°C, 40°F, 10°C
Step-by-step explanation:
-17°C is when F = 0, so -8°C is way higher than -5°F. -8°C comes right after, and 40°F is a bit lower than 10°C. You can convert F to C is °F = (C * 9/5) + 32 and you can convert C to F with (F -32) x 5/9

what is the formed of the fact family for 6,7,13 what is the answer
Answer:
7 + 6 = 13
13 = 7 + 6
13 – 6 = 7
7 = 13 – 6
Step-by-step explanation:
7 + 13 = 20
13 + 7 = 20
13 – 13 = 0
13 – 0 = 13
7 + 0 = 7
6 + 0 = 6
13 – 0 = 13
13 – 13 = 0
7 + 0 = 7
6 + 0 = 6
13 – 0 = 13
13 – 13 = 0
7 + 6 = 13
13 = 7 + 6
13 – 6 = 7
7 = 13 – 6

In a class of 60 children 3/10 we're absent. The rest were present. How many pupils are present.
Answer: 42
Step-by-step explanation:
Answer:
A class of 60 children
3/10 were absent
So we’re trying to find how many pupils are here (kids).
So lets use percentage.
Percentage means out of a hundred so 3/10 is 30/100.
Multiply 10 on each numerator/denominator and you’ll get 30/100.
Now 30/100 is 30 percent.
We are to find 30 percent of 60.
18 pupils are absent.
We’re trying to find who’s here so
60 - 18 = 42
42 pupils are present

Answer:
what are you looking for? are you looking for mean,median,and mode,
Step-by-step explanation:
If so here they are.
Mean=13.1
The mean is the average of the numbers in the data set.
Median=13
The median is the middle number from it being sorted least to greatest.
mode=10,18
The mode is the number that appears most in a data set or sometimes numbers like right now it's numbers,both 10 and 18 appear twice.
Range=15
The range is the highest number subtracted by the lowest number. so what is 19 - 4?it is 15.
minimum=4
The minimum in a data set is the lowest number.
Maximum=19
The maximum is the highest number in a data set.
IQR is 8 because the IQR is based on the lower quartile subtracted by the higher quartile so 18 - 10=8

A population of a town is divided into three age classes: less than or equal to 20 years old, between 20 and 40 years old, and greater than 40 years old. After each period of 20 years, there are 80 % people of the first age class still alive, 73 % people of the second age class still alive and 54 % people of the third age Hare still alive. The average birth rate of people in the first age class during this period is 1.45 (i.e., each person in the first age class, on average, give birth to about 1.45 babies during this period); the birth rate for the second age class is 1.46, and for the third age class is 0.59, respectively. Suppose that the town, at the present, has 10932, 11087, 14878 people in the three age classes, respectively.

The sum of two numbers is 64. The difference between the numbers is 14. Write a system
to find both numbers. Remember to show all work.
Answer:
They say that the sum of the two numbers (x and y) is 64, so we can write our first equation by adding them and setting that sum equal to 64:
x + y = 64
The question also tells us that their difference is 14. Similarly to before, we'll just subtract the two numbers and set that difference equal to 14:
x - y = 14
Now from here, you know how to continue with substitution to find the values for x and y. Just remember when you get a word problem to break it down and look for key words like sum, difference, or product, and from there you'll be able to build your system of equations.
