45 + 11i

To do problems like these, treat them as you would multiplying two binomials. Just FOIL them, and keep in mind that (i)^2 is equal to -1.

Breads/cereals;

11 * 140 = 1540 calories

Fruits/vegetables;

9 * 60 = 540 calories

Meat/milk;

x * 180 = 2800 - (1540 + 540)

180x = 2800 - 2080

180x = 720

x = 4 servings

the area of a right triangle is 336 square centimeters. The base of the right triangle is 48 centimeters. What is the length of
Alex73 [517]

Answer:

50 cm

Step-by-step explanation:

So the first step is to find the height, and to do that you know that the area of a triangle is height * base / 2 =  area. Plugging in the numbers you have, you get:

height*48/2=336

Then, this becomes

height * 24 = 336

Divide both sides by 24

height = 14

Now you can use the base and the height to find the hypotenuse using the Pythagorean Theorem: a^{2} +b^{2} =c^{2}

48^{2} +14^{2} =c^{2} \\2304 + 196 = c^{2}\\2500 = c^2\\50 = c\\c = 50

Therefore the length of the hypotenuse is 50 cm

Answer:

Value of a in term of x = 8/x

Step-by-step explanation:

Given:

14 = ax + 6

Find:

Value of a in term of x

Computation:

⇒ 14 = ax + 6

Step 1; Subtract 6 from both side

⇒ 14 - 6 = ax + 6 - 6

We get step 2

⇒ 8 = ax

Divide x from both side and we get step 3

⇒ 8 / x = ax / x

Step 4

⇒ 8/x = a

Step 5

⇒ a = 8/x

Value of a in term of x = 8/x

Jim has some money ($n) in his pocket and his mum gives him $20. How much poney does he have now?​
liq [111]

Answer:

$n + $20

Step-by-step explanation:

Jim already has $n, and his mom has given him $20. We know we are not taking $n and subtracting $20, since his mom is adding that on to what he already has, we know we are not dividing, not multiplying but adding.

Conclusion : To find how much money he has now you would use the expression $n + $20

Hope this helps, please mark brainliest if possible. Have a nice day.
