Answer:
x = -7/5 y = -6/5
Step-by-step explanation:
System:
y = -2x-4
AND
y= 3x+3
therefore -2x-4 = 3x+3
-2x-3x = 3 + 4
-5x = 7
x = -7/5
y = 3(-7/5) + 3 = -21/5 + 3 = -6/5
Answer:
20 degrees
Step-by-step explanation:
A triangle's angles should 180 degrees added together, so 90 + 70 = 160, leaving 20 for the last angle.
Answer:
The number of tables were used that day at lunch is 23 tables.
Step-by-step explanation:
Given as :
The total number of students in the Polk school = 203
On one day the number of students absent = 19
So, The number of student present on that day = Total student - absent students
I.e The number of student present on that day = 203 - 19 = 184
The number of students sit on each table = 8
Let The number of tables were used that day at lunch = n
<u>So, According to question</u>
The number of tables were used that day at lunch = 
I.e n = 
∴ n = 23 tables
So, The number of tables were used that day at lunch = n = 23 tables
Hence, The number of tables were used that day at lunch is 23 tables. Answer
9514 1404 393
Answer:
72
Step-by-step explanation:
h(4) = 4^3 -2·4 = 64 -8 = 56
g(4) = 3·4 +4 = 16
Then the sum is ...
(h+g)(4) = h(4) + g(4) = 56 +16
(h+g)(4) = 72
