1.) The sum(addition) of 21 and 5 times(multiplication) a number f is(=) 61.
f = unknown number/variable [So 21 plus 5f(5 times f) equals 61]
21 + 5f = 61 [21(one-time) + 5f(number x variable) = 61(total)]
2.) Seventeen more(addition) than seven times(multiplication) a number j is(=) 87.
j = unknown number/variable [So 17 plus 7j(7 times j) equals 87]
17 + 7j = 87
3.) n = number of calls
18 + 0.05n = 50.50
[Company charges $18 plus five cents per call(n), and the total charge was $50.50]
4.) s = the number of students
40 + 30s = 220
[Tutor charges $40 plus $30 per student(s), and the total charge was $220]
Answer:
567 square yards
Step-by-step explanation:
The Area for 1 Triangular playground = 1/2 × Base × Height
The base of the triangle is 18 yards. The height of the triangle is 21 yards.
Hence:
= 1/2 × 18 yards × 21 yards
= 189 square yards
The area of the Triangular 3 playground is given as:
= 3 × 189 square yards
= 567 square yards
54/1,000
just do Length x Width x Height
If they pay $28 for 16 jerseys then the total they’d have to play is $448
28 x 16 = 448
Hope this helps :)
