Answer:
b < 11
Step-by-step explanation:
Given
1 > 5(b - 14) + 16 ← distribute and simplify right side
1 > 5b - 70 + 16
1 > 5b - 54 ( add 54 to both sides )
55 > 5b ( divide both sides by 5 )
11 > b, thus
b < 11
Answer: 60 cappuccinos were sold.
Explanation:
x = number of lattes sold
y = number of cappuccinos sold
Two equations can be set up:
x + y = 78
4x + 3y = 252
The first equation can be rearranged and substituted into the other equation to find the value of a variable.
y = 78 - x
4x + 3(78 - x) = 252
4x + 234 - 3x = 252
x + 234 = 252
x = 18
To find y, the value of x can be substituted into either equation.
x + y = 78
18 + y = 78
y = 60
To check answers, substitute both values into the original equations and make sure they work.
x + y = 78
18 + 60 = 78
78 = 78
4x + 3y = 252
4(18) + 3(60) = 252
72 + 180 = 252
252 = 252
Answer:
0
Step-by-step explanation:
6 - 7 - (-4) - 3
6 - 7 first, and the 4 - 3
-1 + 1
-1 + 1 is 0
0
we are given
S=80
RS=2
we can use tangent formula
now, we can find QR
we will get

Answer:
A integer is any number that is not either a decimal or a fraction (however, both 2.000 and 2/2 are integers because they can be simplified into non-decimal and non-fractional numbers), this includes negative numbers. A whole number is any positive number(0 through infinity) (including non-integers)
Step-by-step explanation:
it's basically a just any number but can't be a decimal or fraction
