Answer:
If the inequality is < or >, graph the equation as a dotted line. If the inequality is ≤ or ≥, graph the equation as a solid line. This line divides the xy- plane into two regions: a region that satisfies the inequality, and a region that does not.
Find the unit price
2.42/16 = 0.15125
1.93/12 = 0.15083 repeating
0.90/6 = 0.15
1.25/9 = 0.138 repeating
The $1.25 one for 9 Oz would be the best buy.
Answer:
x=22.5
Step-by-step explanation:
Make a ratio
The names of the triangle help with this.
AB is similar to FG, and AC is similar to FH (the missing side)
6/15 = 9/x
cross multiply
6x=135
divide both sides by 6
x=22.5
Answer:
A. 47°
Step-by-step explanation:
ΔABC is an isosceles triangles as shown in the picture with two congruent (equal) sides. When the sides are congruent, then the corresponding angles are also congruent. Since ∠A = 4x + 7 and ∠B = 5x - 3, these two expressions are equal to each other:
4x + 7 = 5x - 3
Add 3 to both sides: 4x + 7 + 3 = 5x - 3 + 3 or 4x + 10 = 5x
Subtract 4x from both sides: 4x + 10 - 4x = 5x - 4x or 10 = x
Since x = 10, solve for m∠B: 5(10) - 3 = 50 - 3 = 47°
Less than or equal to $45
