57 of them were cinnamon.
Explanation:
100-40 = 60 and 3 of those were glazed so that leaves us with 57
Answer:
X= 5, -9
Step-by-step explanation:
(X+2)² =49
Expand the bracket,
(X+2) (X+2)= 49
Apply the distributive property;
X(X+2) +2 (X+2) =49
X²+2X+2X+4=49
X²+4X+4=49
Move 49 to the left side of the equation;
X²+4X+4-49=0
X²+4X-45=0
Apply Factorisation method;
Consider the form
a²+bx+c=0
Find two numbers whose sum is equal to b and whose product is equal to c.
Comparing with our equation;
B =4 and C =45
We can use 9 and -5, this is because ;
9+(-5)=4 and 9*(-5)= 45.
Replace X +4X-45=0 with (X-5) (X+9)=0
Therefore;
X-5=0
X+9=0
Moving to the left side of the equation;
Therefore X= 5 and -9
Answer:
D) 5,200
Step-by-step explanation:
The formula to find the area of a r rectangle: l x w, where l is the length and w is width.
Area of the backyard: 50 x 80
= 4,000 ft
Area of the house: 40 x 30
= 1,200 ft
Total = 4,000 + 1,200
= 5,200 ft²
Answer:
Step-by-step explanation:
let : x and t this numbers : x +y = -81/4
y == -52/3
x + (-52/3) = -81/4
x = -81/4 + 52/3........continue
Answer:
Step-by-step explanation:
Given:
Slope (m) = ⁴/3
Point on the line = (x, y) = (3, 2)
Required:
Write the equation in slope-intercept form which is y = mx + b
Solution:
Since we know the slope(m), we need to find the y-intercept (b).
This, substitute (x, y) = (3, 2) and m = ⁴/3 into y = mx + b, and solve for b. Thus:
2 = ⁴/3(3) + b
2 = 4 + b
2 - 4 = b
-2 = b
b = -2
To write the equation, substitute m = ⁴/3 and b = -2 into y = mx + b
