<span>The answer is that x = 21/9.
Start with the original: 4(2x - 1) - 7 = 4 - x + 6
Now distribute the 4:</span> <span> 8x - 4 - 7 = 4 - x + 6.
Now combine the like terms. 8x - 11 = -x + 10.
Now add x to both sides. 9x - 11 = 10.
Now add 11 to both sides. 9x = 21.
And divide by 9 on both side. x = 21/9. </span>

Step-by-step explanation:
Answer:
24 chairs in each class needed
25 classrooms
700 chairs total
how many extra chairs
chairs will be c
t is total
t= 25×c
opposite of multiplication is division( 25 is multiplying by c) c needs to be alone
25 classrooms times chairs equal total chairs
t is 700
700=25×c
700/25=25/25c
700/25=C
c is 28
so 28 chairs for 25 classrooms
they need 24 chairs per class
so there are 4 extra chairs per class
4×25 is 100
**or just multiply 25 classes and 24 chairs
25 times 24 is 600
there are 700 chairs
100 left over
so 100 extra chairs
Answer:x=(y-25)/15
Step-by-step explanation:
Answer:
See explanation below.
Step-by-step explanation:
On the left side of the number line, label it 0. This is Wayne's starting place before he has gone anywhere. On the furthest right of the number line, label it 4 km. This is the total distance he has hiked.
Now divide the space between 0 and 4 into 4 equal parts. This represents each kilometer he hiked.
Divide each of the four sections into 3 equal parts. This means you'll have a total of 12 sections between 0 and 4. Each of these sections is 1/3 of a kilometer. So 4 sections will be 4/3. From zero count 4 sections. Then mark it as 4/3 and break.
Now count from 0, 10 sections or 10/3. Mark this as 10/3 and mark it water break.
