-3y+4x=13
-5y-6x=-67
Answer:
{x,y} = {67/16,-15/4}
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] 2y = -8x + 26
[2] y = -4x + 13
// Plug this in for variable y in equation [1]
[1] 4x + 5•(-4x+13) = -2
[1] -16x = -67
// Solve equation [1] for the variable x
[1] 16x = 67
[1] x = 67/16
// By now we know this much :
x = 67/16
y = -4x+13
// Use the x value to solve for y
y = -4(67/16)+13 = -15/4
Show that x=1 is not a solution to 4x+2 2 = 13.
Answer:
Replacing x = 1 in the equation above, we have: (4x1) + 22 = 13
=> 5 +22 = 13 => 27 [tex]\neq[/tex] 13
So 27 is not equal to 13 => x=1 is not a solution to 4x+22 = 13.

A city has a population of 330,000 people. Suppose that each year the population grows by 3.75%. What will the population be after 7 years?
Use the calculator provided and round your answer to the nearest whole number.
people
5
?
Answer:
429 058 people
Step-by-step explanation:
We will use the population growth formula.
Initial population * e ^ (rate * time)
With the information given, the equation will look like this:
[tex]330000 * e^(0.0375*7)[/tex]
(The numbers in the parantheses are exponents.)
Plug this into the calculator and you will get:
429 058 people.

Shelter A has a capacity of 300 beds and is 60% occupied. Shelter B is 30% occupied. The ratio of the occupancy of Shelter A to Shelter B is 1 : 2. How many beds are in Shelter B?
Answer:
1200 beds
Step-by-step explanation:
Shelter A has a capacity of 300 beds and is 60% occupied.
The amount of beds occupied =
60% × 300 beds
= 60/100 × 300
= 180 beds
Shelter B is 30% occupied.
Let the number of beds in Shelter B = x
30% × x = 0.30x beds
Hence:
180 beds + 0.30x beds
The ratio of the occupancy of Shelter A to Shelter B is 1 : 2.
Let the sum of the proportion = 1 + 2 = 3
Hence:
Number of beds in Shelter B =
2/3(180 beds + 0.30x beds) = 0.3x
2/3(180 + 0.30x) = 0.3x
Cross Multiply
2(180 + 0.30x) = 0.3x × 3
360 + 0.6x = 0.9x
Collect like terms
360 = 0.9x - 0.6x
360 = 0.3x
x = 360/0.3
x = 1200 beds
Therefore, the number of beds that are in Shelter B is 1200 beds

Ten gallons of a 25% salt solution are to be obtained by mixing solutions that are 13% salt and 33% salt
respectively. How many gallons of each are needed?
Answer:
salt + salt = salt
0.13x +3.3-0.33x =2.5
-0.20x=-0.8
x= 4 gallons (amt of 13% solution to be mixed)
10-x= 6 gallons (amt of 33% solution to be mixed)

24 more than the product of 2 and a number.
Enter the correct answer in the box.
Answer:
2x + 24
Step-by-step explanation:
The product of 2 and a number is: 2x
because product means multiply. 2 and a number means 2 times an unspecified number represented as x. 24 more than that product just means to add 24 to the product of 2x.
Answer:2x + 24

A quadrilateral has two angles that measure 10° and 70°. The other two angles are in a ratio of 3:11. What are the measures of those two angles?
Answer:
The measures of those two angles are 60° and 220°
Step-by-step explanation:
The sum of the measures of the angles of any quadrilateral is 360°Let us solve the question
∵ A quadrilateral has two angles that measure 10° and 70°
→ By using the rule above, subtract their measure from 360
∴ The sum of the other two angles = 360° - 10° - 70°
∴ The sum of the other two angles = 280°
∵ The other two angles are in a ratio of 3: 11
→ Find the sum of the parts of the ratio
∵ The sum of the parts of the ratio = 3 + 11 = 14
∵ The sum of the measures of these 2 angles is 280°
→ By using the ratio method
→ m∠1 : m∠2 : their sum
→ 3 : 11 : 14
→ x : y : 280°
→ By using cross multiplication
∵ x × 14 = 3 × 280
∴ 14x = 840
→ Divide both sides by 14
∴ x = 60
∴ m∠1 = 60°
∵ y x 14 = 11 x 280
∴ 14y = 3080
→ Divide both sides by 14
∴ y = 220
∴ m∠2 = 220°
∴ The measures of those two angles are 60° and 220°
