1. 3x+3y=15
-3y = -3y (subtract 3y from both sides)
3x = 15-3y
----------------------
3 = 3 3 (divide each number by 3)
x = 5- y
Answer:
x > -6
Step-by-step explanation:
Here in this question, we have to solve for x from the given inequality
-6 > -30- 4x.
We can solve the inequality equation by using the properties of inequality.
We have, -6 > -30 -4x
⇒ -6+30 > -4x
{The summation and subtraction rules of the inequality equation is similar to that of ordinary equations}
⇒24 > -4x
Dividing both sides by -1, we get,
⇒-24 < 4x
{In case of division of both the sides of an inequality by a negative number, the inequality sign changes from > to < and vice-versa}
⇒4x > -24
Dividing both the sides by 4, we get
⇒ x > -6 {There is same rule as equality equation for division both sides by a positive number} (Answer)
Answer: she had 6 dollars at the beginning of her spree
Step-by-step explanation:
The measure of angle 7 is 61 degrees by the Alternate interior angles theorem.
The alternate interior angles theorem states that, the alternate interior angles are congruent when the transversal intersects two parallel lines. Hence, it is proved. Alternate interior angles can be calculated by using properties of the parallel lines.
