90° counterclockwise rotation
<span>: 2s + 3t = 28, 2s = 28 - 3t s = 14 - 3t/2 Substitute s into second equation 5s + 6t = 61, 5(14 - 3t/2) + 6t = 61, 70 - 15t/2 + 6t = 61, 70 - 3t/2 = 61, 3t/2 = 9, t = 6. We can then substitute t back into first equation: 2s + 3t = 28, 2s + 3 * 6 = 28, 2s = 10, s = 5. So the final answer is: s = 5 t = 6</span>
We can also say this in another way ... (8% of what number is 12?)
let a be the number of which 8 % is 12 ....
<span>8/100 x a =12 </span>
<span>a=12 x 100/8 </span>
<span>a=(6/4) x 100 </span>
<span>a=(3/2) X 100
a = 150 </span>
<span>now if u want to check your answer.. substitute the value of a .....</span>
<span>(8/100) x 150=12 ....
Hope it helps !!!</span>
Answer: She should use 12 ounces of Sweet Rose Tulsi tea and 4 ounces of Orange blossom green tea.
Step-by-step explanation:
Let x represent the number of ounces of Sweet Rose Tulsi tea that she should use.
Let y represent the number of ounces of Orange blossom green tea that she should use.
She wants to blend 16 ounces of the tea blend. It means that
x + y = 16
x = 16 - y
Sweet rose tea sells for $4.98 an ounce and Orange Blossom sells for $1.98 an ounce. If the the tea blend is to sell for $4.23 per ounce, then the 16 ounces would be sold for 16 × 4.23 = 67.68
it means that
4.98x + 1.98y = 67.68- - - - - - - - - - -1
Substituting x = 16 - y into equation 1, it becomes
4.98(16 - y) + 1.98y = 67.68
79.68 - 4.98y + 1.98y = 67.68
- 4.98y + 1.98y = 67.68 - 79.68
- 3y = - 12
y = - 12/-3
y = 4
x = 16 - y = 16 - 4
x = 12
Answer:
The scale will be 1:12
Step-by-step explanation:
Multiply your inches by 12 because there are 12 inches per foot.
