Okay. When there is a square instead of a degree, it just means that it's a 90 degree angle. Good luck!

Answer:

The man has 6 GHc20.00 notes and 4 GHc10.00 left

Step-by-step explanation:

Given

Amount = 3 GH¢50.00, 7 GH¢20.00 and 5 GH¢10.00

Spendings = GH¢80,00

Required

Determine how many GH¢20.00 and GH¢10.00 notes left

The amount he has can be represented as:

$Amount = 3 * GHc50.00 + 7 * GHc20.00 + 5 * GHc10.00$

$Spendings = GHc80.00$

This can be represented as:

$Spendings = GHc50.00+GHc20.00+GHc10.00$

Represent:

GHc50.00 with x, GHc20.00 with y and GHc10.00 with z

So, we have:

$Amount = 3 * GHc50.00 + 7 * GHc20.00 + 5 * GHc10.00$

$Amount = 3 *x + 7*y + 5*z$

$Amount = 3x + 7y + 5z$

$Spendings = GHc50.00+GHc20.00+GHc10.00$

$Spendings =x+y+z$

Subtract the spendings from the total to get amount left

$Amount\ Left= 3x + 7y +5z - (x+y+z)$

$Amount\ Left= 3x + 7y +5z - x-y-z$

Collect Like Terms

$Amount\ Left= 3x-x + 7y-y +5z-z$

$Amount\ Left= 2x + 6y +4z$

Recall that, we have represented:

GHc50.00 with x, GHc20.00 with y and GHc10.00 with z

This means that, the man has 6 GHc20.00 notes and 4 GHc10.00 left

Let f(x)=4x^2-2 f(t+1)

dusya [7]

Answer:

$f(x) = 4 {x}^{2} - 2 \\ f(t + 1) = 4 {(t + 1)}^{2} - 2 \\ = 4( t + 1)(t + 1) - 2 \\ = 4( {t}^{2} + 2t + 1) - 2 \\ = 4 {t}^{2} + 8t + 4 - 2 \\ = 4 {t}^{2} + 8t + 2$

I hope I helped you^_^

Find the value of x. A. About 57.6 B. About 42.6 C. About 12.6 D. About 27.6

nordsb [41]

Answer:

about 27.6

Step-by-step explanation:

The sum of interior angles for this rectangle is 1080

119+140+124+6x+132+132+102 = 1080 add like terms

749 + 12x = 1080 subtract 749 from both sides

12x = 331 divide both sides by 12

x = 27.6 approximately
