Answer:

solution given:

m<a=m<c

3x+40=x+50

3x-x=50-40

x=10/2=5

now

<a=3×5+40=55°

m<a=55° is your answer

Answer:

55°

Step-by-step explanation:

<u>It is assumed the angles A and C are congruent:</u>

3x + 40 = x + 50
3x - x = 50 - 40
2x = 10
x = 5

m∠A = 3*5 + 40 = 55°

Solve the equation and find the value of the variable

djyliett [7]

The sum of the angles should be 180, so x+ (x+10) + (x+5) = 180. This simplifies to 3x + 15 = 180, so 3x = 165, so x=55.

Three-fifths of a number increased by ten

Sav [38]

Answer: $\frac{3}{5} x+10$

Step-by-step explanation:

three-fifths of a number means multiply three-fifths by a variable $\frac{3}{5} x$

increased by 10 means addition +10

together it is $\frac{3}{5}x +10$

Solve the equation for all values of x in simplest form (x + 3)^2 = -16

Arlecino [84]

Answer:

x = -7 or x = 1

Step-by-step explanation:

Given expression:

(x + 3)² = -16

Problem;

Solve for x;

Solution:

To solve for x; we use the factorization method;

Take -16 to the left of the equation;

(x + 3)² = -16

(x + 3)² + 16 = 0

(x+ 3)² + 4² = 0

if x² + y² = (x + y)(x - y)

So;

(x + 3 + 4) (x + 3 - 4) = 0

(x + 7)(x - 1) = 0

x + 7 = 0 or x - 1 = 0

x = -7 or x = 1

Carlos has at most $40 to spend on food for a barbeque. He wants to buy hot dogs and hamburgers and then

poizon [28]

Answer:

$8.50

Step-by-step explanation:

I don't know what Alls are, but if Carlos insists, we can calculate how much he can spend on Alls with the expression:

($31.50) + r $\leq$ $40

This says the sum of what Carlos has already spent (hot dogs and hamburgers) plus the amount he spends on Alls (rolls?), r, must be equal to or less than the $40 he has allowed himself to spend.

($31.50) + r $\leq$ $40

r $\leq$ $40 - $31.50

r $\leq$ $8.50
