300 must be subtracted from the product of 25 and 23 to equal 275.
Answer:
(12, -23)
Step-by-step explanation:
to find x, substitute the value of y into y
-2x+1=-3x+13
collecting like terms
-2x+3x=13-1
x=12
to find y substitute the value x=12 into any of the equation
y=-3x+13
y=-3(12) +13
y= -36+13
y=-23
Refer to the diagram shown below.
The shaded area satisfies the two inequalities
y > x - 1
and
y < 1 -x

Answer: Alonzo sent 15 messages
Kala sent 22 messages
Bill send 60 messages
Step-by-step explanation:
Let x represent the number of messages that Alonso sent during the weekend.
Bill sent 4 times as many messages as alonzo. It means that the number of messages Bill sent is 4x.
Kala sent 7 more messages than alonzo. It means that the number of messages Kala sent is x + 7
Kala, bill alonzo sent a total of 97 text messages during the weekend.
It means that
x + 4x + x + 7 = 97
6x + 7 = 97
6x = 97 - 7 = 90
x = 90/6
x = 15
The number of messages that Bill sent is
4 × 15 = 60
The number of messages that Kala sent is
15 + 7 = 22
