Answer:
1,075
Step-by-step explanation:
4,870-2575=2295
2295-1220=1075
All the opposite angles are equal in a parallelogram:
so AB=DB shows it is an isosceles triangle:
so the two angles on the sides are congruent,
let x to be one of the angles:
2x+28=180
2x=152
x=76=∠A
∠A is opposite of ∠DCB so ∠DCB is 76° because of the parallelogram properties
Answer: y= -22
Step-by-step explanation:
Set up a proportional relationship and solve
If y is -6 and x will be 3 then what will y be when x is 11. \
We can represent that situation like this,
cross multiply
3y = -66 Divide both sides by 3
y = -22
Answer:
The number is 4
Step-by-step explanation:
We set up the equation given the conditions listed. Since it says 5 times the difference between a number and 7, we can use x as a placeholder for the number.
(x-7) is the difference between the number and 7. The question asks for 5 times that difference thus we multiply the entire thing by 5 giving us 5(x-7. The question says that it all equals -15 so we set that expression equal to -15.
Thus we get the equation and solve:
5(x-7)= -15 (distributive property)
5x-35= -15 (add 35 to both sides)
5x=20 (divide by 5)
x=4; so the number is 4
