Answer:
x=1
Step-by-step explanation:
-4+7x=3 add 4 to both sides
7x=7 divide 7 on both sides
x=1
Answer:
no
Step-by-step explanation:
so in order for it to be a right triangle this would have to be true:
a^2 + b^2 = c^2
since c represents the hypoteneuse, it will be the longest side. so:
60^2 + 63^2 = 88^2
3600 + 3969 = 7744
7569 = 7744
since that statement is not true, the answer is no.
it is not a right triangle
the square root of 7569 is 87, so the triple would have to be : {60,63,87}
I did x - 10 =290
+10 +10
-------------
x = 300 so they took $1.00 a day
Answer:
76
Step-by-step explanation:
4(-4(-9)-17)
4(36-17)
4(19)
All the angles should add up to 360°.
8x+10x+9+21x-12+90=360°
Group like terms together.
So,8x+10x+21x+9+90-12=360
39x+87=360
39x=360-87
39x=273
x=7
