Answer:
B) $10.00
Step-by-step explanation:
10 × 18 = 180
10 + 2 = 12
12 × 15 = 180
Answer:
Kabuls = 7.5
Carumpts= 0.85
Step-by-step explanation:
Let x represent the price of kabuls
Let y represent the price of carumpts
8x + 2y= 61.70......equation 1
3x + 10y= 31.........equation 2
Multiply equation 1 by 3 and equation 2 by 8
24x + 6y= 185.1
24x + 80y= 248
-74y = -62.9
y= 62.9/74
y= 0.85
Substitute 0.85 for y in equation 1
8x + 2(0.85) = 61.70
8x + 1.7= 61.70
8x = 61.70-1.7
8x = 60
x= 60/8
x= 7.5
Hence the dollar value for kabuls is 7.5 and carumpts is 0.85
Answer: 7
Step-by-step explanation:
1. multiply both sides by -6 so the -6 on the right side could cancel out and the left side would be -6: 1= a-13/-6 ==> -6=a-13
2. add both sides by 13 so -13 on the right side could cancel out and the left side would be -6+13: -6=a-13 ==> -6+13=a-13+13
3. you know -6+13 equals 7 right? so the answer is a=7
Answer:
v=3
u=6
x=2√2
y=2√2
Step-by-step explanation:
First triangle :
tanΦ=v/3√3
tan30=v/3√3
(√3)/3=v/(3√3)
Cross multiply
(√3)/3 x 3√3=v
(√3 x 3√3)/3=v
(3√9)/3=v
(3x3)/3=v
9/3=v
3=v
v=3
Sin30=v/u
0.5=3/u
Cross multiply
0.5xu=3
0.5u=3
Divide both sides by 0.5
0.5u/0.5=3/0.5
u=6
Second triangle :
sin45=x/4
Cross multiply
x=4 x sin45
x=4 x (√2)/2
x=2√2
Cos45=y/4
Cross multiply
4 x Cos45=y
4 x (√2)/2=y
(4√2)/2=y
2√2=y
y=2√2
Answer:
The correct answer is A) $105
Step-by-step explanation:
In this real-world problem, the cost to groom both dogs is (the puppy) + (the adult dog) = x.
For the first step, y = 40, if x <= 25.
y = 50, if 25 < x < 50.
if x >= 50, then y = 0.50x + 25
So therefore, substitute the puppy + adult dog = x
25 + 80 = x
105 = x
So, the final answer is $105.
