Answer:
6x
Discussion:
7x = 7 times x
x = 1 times x
So both terms are "like" terms in x:
7x - x = (7-1)x = 6x :D

yan [13]

Answer:

As per the statement:

One bread recipe calls for 2 1/3 cup of flour another bread recipe called for to 1/2 cup of flour .

First we calculate how much flour the two recipes combine call for, by adding the amount of flour needed for both the recipes:

⇒ $2\frac{1}{3}+\frac{1}{2}$

⇒ $\frac{7}{3}+\frac{1}{2} = \frac{14+3}{6} = \frac{17}{6}$

Tim would use $\frac{17}{6}$ cup of flour for two recipe.

We have to find how much flour will he have left over.

Tim has 5 cup of flour.

Subtract 17/6 from 5

$5-\frac{17}{6} = \frac{30-17}{6} = \frac{13}{6}= 2\frac{1}{2}$

Therefore, Tim would have $2\frac{1}{2}$ left over.

Let us suppose that one of the fireworks is launched from the top of the building with an initial upward velocity of 150 ft/s an

ivanzaharov [21]

Answer:

9.6 seconds

Step-by-step explanation:

The equation for projectile motion in feet is $h(t)=-16t^2+v_0t+h_0$ where $v_0$ is the initial velocity in ft/s and $h_0$ is the initial height in feet.

We are given that the initial upward velocity is $v_0=150ft/sec$ and the initial height is $h_0=35ft$ . Thus, plugging these values into our equation, we get $h(t)=-16t^2+150t+35$ as our equation for the situation.

The firework will land, assuming it doesn't explode, when $h(t)=0$ , thus:

$h(t)=-16t^2+150t+35\\\\0=-16t^2+150t+35\\\\t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\ \\t=\frac{-150\pm\sqrt{150^2-4(-16)(35)}}{2(-16)}\\ \\t=\frac{-150\pm\sqrt{22500+2240}}{-32}\\\\t=\frac{-150\pm\sqrt{24740}}{-32}\\\\t=\frac{-150\pm2\sqrt{6185}}{-32}\\ \\t=\frac{75\pm\sqrt{6185}}{16}\\\\t_1\approx-0.2\\\\t_2\approx9.6$

Since time can't be negative, then the firework will land after 9.6 seconds, assuming it doesn't explode at the time of landing.

Softa [21]

Answer:

She takes 11 grams more protein for breakfast than for a snack.

Step-by-step explanation:

Consider the provided information.

Gina had a scrambled egg and a cup of low-fat milk for breakfast.

She had an oat bran muffin for a morning snack.

First round up the numbers as shown below:

Food Protein (in grams) 1 scrambled egg 6.71 ≈ 7

1 cup shredded wheat cereal 5.51 ≈ 6

1 oat bran muffin 3.98 ≈ 4

1 cup low-fat milk 8.22 ≈ 8

Protein in Breakfast = a scrambled egg + a cup of low-fat milk

Protein in Breakfast = 7+8 = 15

Morning snack she had an oat bran muffin.

Protein in Morning snack = 4

Now we need to find how many more grams of protein did Gina have for breakfast than for a snack?

So subtract them as shown below:

15-4 = 11

Hence, she takes 11 grams more protein for breakfast than for a snack.
