Answer:
-6000
Step-by-step explanation:
20{5[100-3(25+35)+20]} open the parenthesis
20{5[100-180+20]} do the addition and subtraction in the square brackets
20{5[-60]} open the square brackets
20{-300} open curly brackets
-6000
The answer is 50 & 24
x - the bigger number
y - the smaller number
<span>The sum of a number and two times a smaller number is 98:
x + 2y = 98
</span><span>The bigger number is 22 less than three times the smaller number:
x = 3y - 22
</span>x + 2y = 98
x = 3y - 22
________
3y - 22 + 2y = 98
5y - 22 = 98
5y = 98 + 22
5y = 120
y = 120/5
y = 24
x = 3y - 22
x = 3 * 24 - 22
x = 72 - 22
x = 50
Answer mon
Step-by-step explanation:
Answer:
let the third side be x
Using pythagoras theorem we get,
(58)^2 = (42)^2 + (x)^2
3364=1764+x^2
x^2=3364-1764
x^2= 1600
x=√(1,600)
x=40
Answer:
60cm²
Step-by-step explanation:
Surface area of a triangular prism = 2B+ph
B is the base area = 6cm²
perimeter p = 12cm
altitude h = 4cm
Substitute
Surface area = 2(6) + 12(4)
Surface area = 12 + 48
Surface area = 60cm²
