7x= 28 so x is 4 and y is 1.. So (4,1)
Answer:
Answer: x= -6 and y= -7
Step-by-step explanation:
Substitute 2x+5 for y in y=3x+11:
y=3x+11
2x+5=3x+11
2x+5+−3x=3x+11+−3x(Add -3x to both sides)
−x+5=11
−x+5+−5=11+−5(Add -5 to both sides)
−x=6
−x−1=6−1(Divide both sides by -1)
x=−6
Step: Substitute −6 for x in y=2x+5:
y=2x+5
y=(2)(−6)+5
y=−7(Simplify both sides of the equation)

Answer: 10 verticesTo make a full circle(360 °), the number of 40° lines you need will be: 360/40=9 lines. So, the base of the pyramid would be made of 9 lines.Pyramid has a base and sides. The sides number is equal to the number of lines of the base. Then, the number of faces/vertices would be: 1 + 9= 10
If the question saying literally 40 edges(not degrees), then the pyramid base would be 40 lines. In this case, the number of vertices would be: 1+40=41

Answer:
52°, 40°, 88°
Step-by-step explanation:
Let x represent "one angle". This is 30% larger than "the other", so we have ...
x = "the other" × (1 +30%)
x/1.30 = "the other"
If x is 36° smaller than the third, then the third is x+36.
__
The sum of the angles is 180°.
x + x/1.3 + (x +36) = 180
x(2 +1/1.3) = 144
x = 144/(2 +1/1.3) = 52
x/1.3 = 52/1.3 = 40
x +36 = 88
The angles of the triangle are 52°, 40°, and 88°.
