Answer:
The equations 9x+8y=14100 and x = y+150 are in the simplest form.
Step-by-step explanation:
Given that:
Russian blue kitten costs $150 more than Manx kitten.
Cost of 9 blue kittens and 8 Manx kittens = $14100
Let,
x be the price of one Russian blue kitten.
y be the price of one Manx kitten.
According to given statement;
9x+8y=14100
x = y+150
Hence,
The equations 9x+8y=14100 and x = y+150 are in the simplest form.
Answer:
A
Step-by-step explanation:
Answer:
Amount required = 2,217,600
Step-by-step explanation:
Dimensions of the rooms are as follows;
Room 1; 9 feet × 12 feet
Room 2; 14 ft × 16 ft
Room 3; 12 ft × 14 ft
Perimeter of rooms;
P1 = 2(9 + 12) = 42 ft
P2 = 2(14 + 16) = 60 ft
P3 = 2(12 + 14) = 52 ft
Total perimeter; P = 42 + 60 + 52 = 154 ft
Height is 90 ft.
Thus, total area is;
A = 154 × 90
A = 13860 ft²
Rate of painting is 160 per Sq.ft.
Thus amount to paint entire area = 160 × 13860 = 2217600
First you need to set up a formula. Underline all of your givens:
<u>Spent 1/2 on clothes
$6 more for washing windows
Ended with $10.
</u>
now you need to set up an equation.
<u>
</u>You know she ended up with $10. So that will be what it equals. Then you know that she earned $6 in addition to her allowance. So this would be (x= allowance) (x+6)/2 = 10.
<u>
</u>Now you need to solve for x.
Multiply both sides by 2.
<u>
</u>x+6=20<u>
</u>Now subtract both sides by 6 to get x alone:
<u>
</u>x=$14<u>
</u><u>
</u>
