i have i need to use the substitution method to work out what x and y is
5y−2x=10
8x+5y=60
Answer:
pick the simplest of the 2 equations
Step-by-step explanation:
5y-2x=10
5y = 2x +10
y = 2/5x + 2
now substitute
8x + 5(2/5X +2)=60
8x + 2x + 10 = 60
10x = 50
x = 5
y = 4
Harold is designing a patio with congruent square concrete tiles. He has 72 tiles. Use grid paper to model all the possible rectangular patios Harold could build. Label the dimensions in units. Which patio has the greatest perimeter? The least perimeter?
Answer:
(a) The possible dimensions are:
1 unit by 72 units; 2 units by 36 units; 3 units by 24 units; 4 units by 18 units; 6 units by 12 units; 8 units by 9 units
(b): Patio with greatest and the least perimeter
The dimension with the greatest perimeter is: 1 by 72
The dimension with the least perimeter is: 8 by 9
Step-by-step explanation:
Given
[tex]Tiles = 72[/tex]
Solving (a): Possible rectangular models
To do this, we simply list out the possible factor pairs of 72.
So, we have:
1 unit by 72 units; 2 units by 36 units; 3 units by 24 units; 4 units by 18 units; 6 units by 12 units; 8 units by 9 units
Solving (a): Models with the least and the greatest perimeter
Perimeter (P) is calculated using:
[tex]P = 2 * (L + W)[/tex]
So:
1 unit by 72 units;
[tex]P = 2 *(1 + 72) = 146 units[/tex]
2 units by 36 units;
[tex]P = 2 *(2 + 36) = 76 units[/tex]
3 units by 24 units;
[tex]P = 2 *(3 + 24) = 54 units[/tex]
4 units by 18 units;
[tex]P = 2 *(4 + 18) = 44 units[/tex]
6 units by 12 units;
[tex]P = 2 *(6 + 12) = 36 units[/tex]
8 units by 9 units
[tex]P = 2 *(8 + 9) = 34 units[/tex]
From the calculations above:
The dimension with the greatest perimeter is: 1 by 72
The dimension with the least perimeter is: 8 by 9

work out: 0.03 x 0.6
0.03 x 0.6
= (3 x 6) / 1000
= 18 / 1000

If 48% of the students in a certain college are female and there are 2,400 female students, how many students are male?
Answer:
2,600 male students
Step-by-step explanation:
[tex]\frac{2,400}{0.48} = 5,000[/tex]
There are 5,000 students in total.
Since 2,400 of them are female, the remaining students must be male.
5,000 - 2,400 = 2,600 male students

two times the sum of a number and 18 is at least -21
Answer:
2x + 18 ≥ 21
x ≥ 2/3
Step-by-step explanation:
Let sum be X
2 times the sum means 2x
the sum of a number and 18 means x + 18
at least -21 means ≥ 21
put them together, and you get, 2x + 18 ≥ 21
If solving for x,
2x + 18 ≥ 21
2x ≥ 3
x ≥ 2/3

Can some tell me which one is correct and how to answer the “ how do you know” part
Answer:
Student B
Step-by-step explanation:
You know because:
The common factor between 3 and 6 is 3.
You can factor 2 x's from both parts and 2 y's.
Therefore, it would be
3x^2y^2.

A gym charges an initial fee plus $25 per month. John paid $200 for six months. Assume the relationship is linear.
a.What is the rate of change and what does it mean in context to the situation?
b. What is the initial value and what does it mean and context to the situation?
i will give brainliest!!!!!
Step-by-step explanation:
a. The rate of change is $33.33 per month
200/6 = approximately $33.33 per month
This means that in addition to the initial fee, Josh has to pay $33.33 per month for the gym membership.
b. The initial value is $25. This is a constant value and a one time fee to open and attain a gym membership.

Which planet in the chart is most likely Earth? Yeah
Does somone no the answer
Answer:
Kepler-452b has a probable mass five times that of Earth, and its surface gravity is nearly twice as Earth's, though calculations of mass for exoplanets are only rough estimates. If it is a terrestrial planet, it is most likely a super-Earth with many active volcanoes due to its higher mass and density.Step-by-step explanation:
