Well knowing that it’s 5 1/4 and the cost of paint is 13.99, I’m going to assume to multiply by the given product which is 13.99 by one quarter (which is 25)
Answer:
A salad costs $2.50
A sandwich costs $4.50
A drink costs $1.25
Step-by-step explanation:
Let x represent the salad, y represent the sandwich, and z represent the drink.
Since three salads, two sandwiches, and one drink cost $17.75:
3x + 2y + z = 17.75 (1)
Since one salad, one sandwich, and three drinks cost $10.75:
x + y + 3z = 10.75 (2)
Since a salad costs twice as much as a drink:
x = 2z (3)
Multiply the equation 2 by -2 then, sum the equation 1 and equation 2:
-2x - 2y - 6z = -21.50
3x + 2y + z = 17.75
→ x - 5z = -3.75
Replace the x with 2z using equation 3:
2z - 5z = -3.75
-3z = -3.75
z = 1.25
x = 2z → x = 2.50
x + y + 3z = 10.75 → 2.50 + y + 3.75 = 10.75 → y + 6.25 = 10.75 → y = 4.50
Hello, so a simple way to do it is to cross cancel and then you would end up with 7/4 x 1/3 and it would equal 7/12 and that’s in simplest form.
Answer:
S.A = 730mm²
Step-by-step explanation:
Since the solid is made up of two rectangles. Then the surface area (S.A) would be
S.A = area of first rectangle + area of second rectangle
Since the first rectangle has it's base to be 25mm and height to be 21mm, then it's area is
25mm x 21mm = 525mm²
Since the second rectangle has it's base to be 41mm and height to be 5mm, then it's area is
41mm x 5mm = 205mm²
Therefore
S.A = 525mm² + 205mm² = 730mm²
Side of a square=s=3⁵/² in
A=s²
A=(3⁵/² in)²=3¹⁰/² in²=3⁵ in²=243 in²
answer. 243 in²
