Step-by-step explanation:

Let F represent fruitshake and C chocolate milkshake

one fruitshake cost more 2R more than chocolate shake and

3F + 5C = R78,00

Then (78 - 6) ÷ 8 = 9

a fruitshake costs R11,00 and chocolate milkshake costs 9R,00

I'll give a brainliest <br>Find the integers which satisfy the inequality. - 5 &lt; 2n - 1 ≤ 5<br>​
ella [17]

Answer:

-1, 0, 1, 2, 3

Step-by-step explanation:

Solve two equations:

-5 < 2n-1 => -4 < 2n => n > -2

and

2n-1 ≤ 5 => 2n ≤ 6 => n ≤ 3

so

-2 < n ≤ 3

then enumerate the possible values for n

-1, 0, 1, 2, 3

Consider a triangle ABC
N76 [4]

Answer:

A =24.7° ; B = 40.6° ; C =114.7°

Step-by-step explanation:

Cosine Law

a² = b²+c²-2bc cos A

b² = c²+a² -2ca cos B

Sum of three angles of a triangle is 180°.

a = 34 ; b= 53; c = 74

Substituting the given values in the cosine law, we have

34² = 53² + 74² - 2*53 *74 * cos A

7844 cos A = 2809 + 5476 - 1156 = 7129

cos A = 7129/7844 = 0.9088

A = cos⁻¹ (0.9088) = 24.6600° = 24.7°

53² = 74² + 34² - 2 (74)(34) cos B

5032 cos B = 5476 + 1156 - 2809 = 3823

cos B = 3823/5032 = 0.7597

B = cos⁻¹ (0.7597) = 40.5622° = 40.6°

Also, A + B + C = 180°

24.7 + 40.6 + C =180

C =180 -  65.3 = 114.7°

∴ A =24.7° ; B = 40.6° ; C =114.7°

valentina_108 [34]

Let x represent the number of ounces of vinegar

Let y represent the number of ounces of lemon juice

Oil required = 8 oz

Container can hold = 16 oz

So the inequality equation will be :

B. Simplify: 3(x+2) = 4x ( +2 points)
olya-2409 [2.1K]

Answer:

6

Step-by-step explanation:

3(x+2) = 4x

3x + 6 = 4x  <- you times the x and 2 that is inside of the parentheses by the 3 that is on the outside

3x - 3x + 6 = 4x - 3x  <- you have to subtract the 3x from the left side and you have to do the same on the right so you can get the numbers alone.

6 = x
